✦ Synopsis

The spectrum of isotopically substituted carbon disulfide has been studied in the region near the n 2 vibration (400 cm 01 ). The fundamental and six hot bands of 12 C 34 S 2 were recorded at a resolution of 0.01 cm 01 , as were four bands of 12 C 32 S 34 S and two bands of 13 C 34 S 2 . The observed line positions were reproduced by the effective Hamiltonian with a RMS error of 0.001 to 0.005 cm 01 . Normal and internal coordinate anharmonic force constants for CS 2 are reported.

The infrared spectrum of the deuterated hydroxyl radical OD has been measured with a Fourier transform spectrometer between 1850 and \(9000 \mathrm{~cm}^{-1}\). The source, a deuterium atom ozone diffusion flame, was designed to study the chemilumineseent excitation of the vibration-rotation energy

The HCCN radical is known to be a quasi-linear molecule in its ground triplet state ( 3 -in the linear configuration). Vibration-rotation transitions in the HCC bending (ν 5 ) fundamental band have been detected around 129 cm -1 by the technique of far-infrared laser magnetic resonance (FIR LMR). Fo
