Submillimeter wave spectrum and molecular constants of N2O

摘要: Abstract The submillimeter wave spectrum of the N2O molecule has been investigated within 375–565 GHz frequency range with a sensitivity better than 10−8 cm−1. measured frequencies include 161 lines intensities γ ≳ 10−6 cm−1 belonging to 22 spectroscopically different species (specifically, ground and some excited vibrational states five most abundant isotopic in natural abundance) statisticall systematic error order magnitude 10−8. Rotational two centrifugal stretching constants could be determined for each spectroscopic species. For observed, we have made general analysis bearing mind resonance effects. total number rotational rovibrational obtained exceeds 40.
