Evaluation of intensity information in high-resolution gas-phase Fourier transform infrared spectra. Invited lecture

Abstract

The strategies for the exploitation of intensity information in high resolution Fourier-transform infrared spectra are reviewed. Results of the evaluation of rotationally resolved and also partially resolved spectra are presented, including different types of quantitative information. The questions addressed are the equilibrium abundance of HNCNH in H₂NCN, accurate intensity data for the 350 cm^–1 band of N₂O₅, the transition moment of a ‘forbidden’ band in HCNO, and line parameters for the bending mode v₅ of NCCN.
