Infrared Transitions of H12C14N and H12C15N between 500 and 10000 cm−1

摘要: Abstract We have measured the Fourier transform spectrum (FTS) of two isotopomers hydrogen cyanide (H 12 C 14 N and H 15 N) from 500 to 10 000 cm −1 . The infrared data been combined with earlier published microwave submillimeter-wave measurements. From this analysis new vibration–rotation energy levels constants are given, based on observation a number vibrational levels, especially for N. Coriolis interaction involving Δ v 3 = −1, 2 3, l ±1 has observed great many in some cases assignments laser transitions allowed by more clearly shown. New given that allow one predict transition wavenumbers most below accuracies about 0.5 or better. Values power series expansion -type resonance centrifugal distortion constants, as well usual rotational constants.
