甲酸的亚毫米光谱
Submillimeter Spectrum of Formic Acid
摘要：
我们已经测量了新的亚毫米波数据约600 GHz和约1.1太赫兹的13 C同位素的甲酸和两个氘同位素异构体;在每种情况下的反式和顺式旋转异构体。特别是对于顺式-DCOOH和顺式-HCOOD，以前只有高达50 GHz的数据可用。对于所有物种，分子参数的质量和数量都得到了提高，在现有和不久的将来亚毫米和远红外天文光谱仪器，如Herschel，SOFIA和ALMA的范围内提供了新的测量频率和更精确和可靠的频率。
英文摘要：
We have measured new submillimeter-wave data around 600 GHz and around 1.1 THz for the 13C isotopologue of formic acid and for the two deuterium isotopomers; in each case for both the trans and cis rotamer. For cis-DCOOH and cis-HCOOD in particular only data up to 50 GHz was previously available. For all species the quality and quantity of molecular parameters has been increased providing new measured frequencies and more precise and reliable frequencies in the range of existing and near-future submillimeter and far-infrared astronomical spectroscopy instruments such as Herschel, SOFIA and ALMA.
