Anomalies in the pure rotation spectrum of fluoroform in excited vibrational states

摘要: Abstract Theoretically, the K = 0 levels of a symmetric top can have only quadratic Stark effect, but in J 1 ← spectrum CHF3, rotation lines three excited vibrational states linear with displacements Δv 5 ±0.82 × 10 −2 ϵ Mc/sec, 4 ±2.30 Mc/sec , 2 ±2.16 . No effect could be detected for these lines. Their line width is one third that normal lines, lobes broaden very rapidly as field increased. The CDF3 entirely normal, and α′s were measured five six fundamental vibrations. value α1 CD stretching vibration was obtained from high-resolution study ν1 band, therefore Be 9999.20 obtained. In CHF3 ν6, displaced 14.7 its expected position, has four lobes. CDF3, 1, split into spread over 157 Mc/sec. At least two are degenerate effect. This splitting indeed puzzling, since species E, it normally considered cannot by any interaction rotation. explanation offered anomalies.
