MICROWAVE SPECTRUM OF 2,3,4-TRICARBAHEXABORANE (7)

Abstract

The microwave spectrum of $C_{2}B_{3}H_{7}$ (2,3,4-tricarbahexaborane (7)) has been investigated in the frequency range of 8-38 GHz. An analysis of the Q-branch spectra facilitated the spectral assignments by allowing calculation of the differences between the three rotational constants of this near oblate rotor. The rotational constants for the normal isotopic species are: A=6506.49$\pm$0.04 MHz, B=6382.17$\pm$0.02 MHz, C=4203.84$\pm$0.04 MHz.
