NIST Recommended Rest Frequencies for Observed Interstellar Molecular Microwave Transitions—2002 Revision Frank J. Lovasa… Optical Technology Division, National Institute of Standards and Technology, Gaithersburg, Maryland 20899-8441 共Received 23 January 2003; revised manuscript received 3 June 2003; accepted 30 April 2003; published online 26 February 2004兲 Critically evaluated transition frequencies for the molecular transitions detected in interstellar and circumstellar clouds are presented. The tabulated transitions are recommended for reference in future astronomical observations in the microwave and millimeter wavelength regions. The transition frequencies have been selected through a critical examination and analysis of the laboratory spectral data obtained from the literature. The information tabulated includes the species identity, transition frequency, uncertainty, and quantum state labels. For convenience, representative line antenna temperatures are listed for a typical astronomical source for each transition, and the references are cited for the laboratory and astronomical literature that have been employed. © 2004 by the U.S. Secretary of Commerce on behalf of the United States.

Sources and Selection of Transition Frequencies 180 The present tabulation covers the astrophysical literature through December 2002. The 114 molecular species listed in Table 1 have now been identified in interstellar and circumstellar astronomical sources by means of their microwave spectra. The 22 additional interstellar species, identified by their infrared or ultraviolet spectra, and comet molecular species are listed in Table 2. Since no microwave transitions of these species have been reported yet, there will be no entries in Table 4 for these species. The sources of the transition frequencies selected are as follows: laboratory measurements and predictions from the literature data, previously published tabulations of spectral frequencies,4 –27 spectral predictions of transition frequencies from reanalysis of the literature data carried out in the present work, and web-based catalogs.26,27 The primary criterion for selection of the transition frequencies is the magnitude quoted for the estimated uncertainty in the measured frequency or the standard deviation of calculated frequencies. For well-behaved species, i.e., those whose spectra are well fit by established Hamiltonians, the calculated frequencies are often more accurate than individual measurements, 184 184 185 1. Introduction The present tabulation of recommended transition frequencies for interstellar molecular species is the third revision of the previously published tables.1–3 Since the last revision in 1991, approximately 5600 new transitions and 31 new molecular species have been added to the table which a兲 Electronic mail: [email protected] © 2004 by the U.S. Secretary of Commerce on behalf of the United States.

LOVAS thus many of the entries in Table 4 are calculated values and are identified with an asterisk ( * ) following the frequency entry. In entries where it was determined that the measured value had the lowest uncertainty value, a reference to the literature value is given. For many of the interstellar species the previously published tabulations of critically evaluated laboratory data4 –25 were the source of both measured and calculated frequencies cited here. In many cases for species treated in the publications indicated above, new spectral data have been reported and have been combined with the earlier data sets and reanalyzed to provide predicted frequencies employed here. Some of the earlier reviews also have a frequency limit of 200 or 300 GHz, while new interstellar observations range up to 725 GHz. Thus, for most of the smaller species 共diatomic, triatomic, etc.兲 calculations were extended to higher frequencies with new laboratory data included where available. The earlier reviews on CH3 OH, 6 CH3 CHO, 12 and HCOOCH3 19 are outdated and new reviews were used 共关Xu – 97兴, 关Kle91兴, and 关Oes99兴兲. In a few cases, e.g., for radical species such as C2 H, C3 N, C4 H, etc., the on-line catalogs developed at the Jet Propulsion Laboratory 共JPL兲26 and at the University of Cologne27 were used as the source of calculated frequencies. 3. Description of the Tables Table 1 provides the identity of molecular species detected in astronomical sources in the radio, microwave, millimeter, and submillimeter region. For a number of the species one or more isotopically substituted forms have been observed and these are listed as well in Table 1. In Tables 1 and 2 the species are listed in alphabetic sequence according to empirical formula 共Hill system兲 in the first column along with the common names of the molecule in the second column, and molecular formula in the third column. The reference共s兲 given in the last column of Tables 1 and 2 are for the original detection in the astronomical source. Table 3 provides the code and identification of the telescope used in the astronomical reference for each transition in Table 4. The major emphasis of the present work is to provide the most accurate transition frequencies available for all of the astronomically observed spectral lines which are listed in Table 4. In Table 4 the recommended frequency is listed in column 1, followed by an asterisk in the case of calculated values, and its expanded uncertainty (k⫽2 or 2␴兲 is shown in units of the least significant digit共s兲. Uncertainties28 for calculated frequencies are Type A with coverage factor k ⫽2 共2 s.d.兲. For measured frequencies, the uncertainties are Type B and taken directly from the reference cited. The chemical formula for each molecular species is given in column 2, the chemical name in column 3, and the quantum number labels are shown in column 4. Columns 5, 6, and 7 present astronomical information: antenna temperature (T r* or T a* ) or integrated intensity 共full line width at half intensity times peak intensity兲 molecular cloud for the observation and J. Phys. Chem. Ref. Data, Vol. 33, No. 1, 2004 abbreviation for the telescope employed 共see Table 2 for a list of telescopes referenced兲, respectively. Most often the molecular cloud listed is Orion A 共OriMC-1兲, Sagittarius B2 共SgrB2兲, Taurus Molecular Cloud 1 共TMC-1兲, or the circumstellar envelope of the infrared star IRC⫹10216, since these are the richest molecular sources and often provide the most intense emission lines. In column 8 the reference abbreviation for the astronomical observation is given and column 9 shows the reference to measured 共or calculated兲 frequencies when taken from the literature. The reference code is based on the first three letters of the lead author’s last name, plus the last two digits of the year of publication. If no laboratory reference appears, the frequencies presented are calculated in the present work. The reference list for Tables 1, 2, and 4 then follows Table 4. 4.
