Abstract
Resent results of millimeter and submillimeter wave rotational spectroscopy of the $\nu_{5}/2\nu_{9}$ states of nitric $acid^{a}$ are used to simulate the complex structure of the $2\nu_{9} - \nu_{9}$ and $\nu_{5}- \nu_{9}$ hot bands near $22\mu$. The comparison data were obtained with a high resolution Bruker FTIR at various pressures and a temperature of 297 K. The combination of the quality and resolution of the infrared data and the complexity of the spectra of these interacting states represents a stringent test for the simulation. It is shown that the agreement is very good and that this approach is generally advantageous.
