ExoMol line lists for HNO3

Listed in IVOA Registry (Virtual Observatory)

Nitric acid is a possible biomarker in the atmospheres of exoplanets.

Description

An accurate line lists is computed for nitric acid (HNO3). This line list covers wavelenghts longer than 1.42 um (0-7000cm^-1^) and temperatures up to 500K.

The line list is computed using a hybrid variational-perturbation theory and empirically tuned potential energy and dipole surfaces. It comprises almost 7 billion transitions involving rotations up to J=100. Comparisons with spectra from the HITRAN and PNNL databases demonstrate the accuracy of our calculations.

Synthetic spectra of water - nitric acid mixtures suggest that nitric acid has features at 7.5 and 11.25um are capable of providing a clear signature for HNO3; the feature at 11.25um is particularly promising. Partition functions plus full line lists of transitions are made available in an electronic form as supplementary data to the article and at www.exomol.com.
