The tabulated transition frequencies are recommended for reference in future astronomical observations in the centimeter 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. 2009 Revision"],"keyword":["astronomy","atomic physics","circumstellar clouds","interstellar molecules","microwave spectroscopy","molecular clouds","molecular lines","physics","radio astronomy","rotational spectra"],"theme":["Standards: Reference data","Chemistry: Analytical chemistry","Physics: Atomic, molecular, and quantum"],"topic":[{"@type":"Concept","scheme":"https://data.nist.gov/od/dm/nist-themes/v1.1","tag":"Standards: Reference data"},{"@type":"Concept","scheme":"https://data.nist.gov/od/dm/nist-themes/v1.1","tag":"Chemistry: Analytical chemistry"},{"@type":"Concept","scheme":"https://data.nist.gov/od/dm/nist-themes/v1.1","tag":"Physics: Atomic, molecular, and quantum"}],"references":[{"@type":["deo:BibliographicReference"],"@id":"#ref:PhysRefData/Micro/Html/sec2.html","refType":"IsSupplementTo","location":"http://physics.nist.gov/PhysRefData/Micro/Html/sec2.html","_extensionSchemas":["https://data.nist.gov/od/dm/nerdm-schema/bib/v0.7#/definitions/DCiteReference"]}],"accessLevel":"public","license":"https://www.nist.gov/open/license","inventory":[{"forCollection":"","childCount":1,"descCount":1,"byType":[{"forType":"dcat:Distribution","childCount":1,"descCount":1},{"forType":"nrdp:AccessPage","childCount":1,"descCount":1}],"childCollections":[]}],"components":[{"accessURL":"https://dx.doi.org/10.18434/T4JP4Q","mediaType":"text/html","@type":["nrdp:AccessPage","dcat:Distribution"],"@id":"#10.18434/T4JP4Q","_extensionSchemas":["https://data.nist.gov/od/dm/nerdm-schema/pub/v0.7#/definitions/AccessPage"]}],"publisher":{"@type":"org:Organization","name":"National Institute of Standards and Technology"},"language":["en"],"bureauCode":["006:55"],"programCode":["006:052"],"version":"1.0.0"},
