✦ Synopsis

The Fourier transform absorption spectrum of HONO was recorded at high resolution between 600 and (12000 \mathrm{~cm}^{-1}) using various experimental conditions. The results concerning the trans isomer are presented; i.e., the full rovibrational analysis of the (\nu_{1}, \nu_{2}, \nu_{3}, \nu_{4}), and (2 \nu_{1}) bands and the vibrational analysis and band contour simulation of the (2 \nu_{2}, \nu_{1}+\nu_{4}, \nu_{1}+\nu_{3}, \nu_{1}+2 \nu_{3}), and (3 \nu_{1}) bands have been given. The results are combined with those of previous literature investigations to obtain a complete set of rovibrational parameters, including equilibrium rotational parameters, (A_{\mathrm{e}}=3.122 \mathrm{~cm}^{-1}, B_{\mathrm{e}}=0.4230 \mathrm{~cm}^{-1}), and (C_{\mathrm{e}}=0.3724 \mathrm{~cm}^{-1}). cc 1993 Academic Press.
