Effect of Coriolis Interaction on the Decay of Isotones with N = 149 and N = 153

The infrared spectra of two B type bands, ν2 and 2ν1, of 14N16O2 have been recorded under high resolution. Ground state combination differences from these bands have been combined with combination differences obtained in previous studies and eight pure rotational microwave transitions to yield improved ground state rotational constants. Upper state constants and band centers for the ν2 and 2ν1 bands are also reported. The 2ν1 band contains internal intensity anomalies believed to arise from a weak Coriolis interaction with the much stronger ν1 + ν3 band. Equilibrium rotational constants have been calculated. The equilibrium structure of the molecule is: rc = 1.1945 ± 0.0005 Å and Θc = 133.85 ± 0.10°. For the sake of comparison, effective, substitution, and average structures are also reported.

Methyl Torsion

The rotational spectrum of ethyl acetylene has been investigated between 70 and 320 GHz. A Coriolis interaction has been found between the first excited state of the methyl torsion and the C - C = C in plane deformation. Splittings of transitions in the first excited torsional state show that the barrier hindering internal rotation of the methyl group amounts to 3271 cal/mole.

Tunable Diode Lasers

The v 3 band of NF 2 (X̃ 2 B 1 ) has been measured at high resolution by using tunable diode lasers. Rotational, distortion and spin-rotation constants have been derived for the v 3 = 1 state by using ground state constants derived earlier from analysis of the v 1 band. The position of the band centre, not previously measured, is 942.481 53(30) cm -1 . Analysis of the v 1 — v 3 Coriolis interaction yields the Coriolis coupling constant ξ 13 = 0.698(10).
