Temperature dependence of nitrogen and oxygen-broadening of the¹⁶O₃υ₁band

Abstract

High-resolution Fourier transform absorption spectra of ozone broadened by N 2 and O 2 have been recorded at room temperature and at 225 K. Nitrogen and oxygen-broadened half-widths and their temperature dependence have been determined for 40 ro-vibrational transitions of the 16 O 3 1 band near 1103 cm À1 with a wide range of the rotational quantum number J (12-40) have been determined.

Studies of IR absorption ozone spectra between 2000 and 2015
