Abstract: | Studies of five comparatively unperturbed infrared active bands in the spectrum of 10B2D6 were undertaken with a resolution of ca. 0.05 cm−1. These comprise three type-A bands (ν17, ν18, and ν5 + ν15), one type-B band (ν8), and one type-C band (ν14). Ground-state rotational and quartic centrifugal distortion constants were determined for the first time from a total of over 400 combination differences. Sets of upper-state parameters were determined for all five bands studied, and the effects of a number of minor Coriolis interactions between fundamental vibrations are discussed. |
