Frequency and intensity measurements in the fundamental infrared band of HD

The fundamental band of HD has been studied at room temperature and 0.6 atm pressure with a 48-m absorption path and a resolution of 0.01 cm −1. The frequencies of nine electric dipole and three electric quadrupole transitions were measured with an accuracy of 0.001 cm −1, and their analysis gives i...

Description
Summary:The fundamental band of HD has been studied at room temperature and 0.6 atm pressure with a 48-m absorption path and a resolution of 0.01 cm −1. The frequencies of nine electric dipole and three electric quadrupole transitions were measured with an accuracy of 0.001 cm −1, and their analysis gives improved molecular parameters for the v = 0 and 1 states of HD. The intensities of the dipole transitions were measured in order to determine the v = 1-0 electric dipole transition moment. These measurements extend earlier experiments to higher J values, thus refining the determination of the rotational dependence of the transition moment.
