Hydrogen chloride

Energy levels, transition frequencies and Einstein A coefficients for the HCl rotation spectrum with hyperfine structure are taken from the JPL database, version 3 of May 2012. Collision rates are taken from Lanza et al (2014) and were calculated for temperatures in the range from 10 to 300 K including energy levels up to 1400 cm-1 above the ground state. The rates were neither scaled nor extrapolated and are valid for both common isotopologs of HCl.
