Energy levels, transition frequencies and Einstein A coefficients were taken from the JPL catalog. The collisional rates are taken from Danby et al. (1988) and were calculated for temperatures in the range from 15 to 300 K including energy levels up to about 420 cm-1 for collisions with para-H2. At present no extrapolated rate coefficients are made available.
More recent calculations by Maret et al (2009) use a more accurate interaction potential, but cover a smaller temperature range and do not treat hyperfine structure.
For NH2D, we provide collision data by Daniel et al (2014), which cover energy levels up to 512 cm-1 for collisions with ortho- and para-H2 at temperatures from 5 to 300 K. The spectroscopy for this species is taken from the CDMS catalog.
