Energy levels, transition frequencies and Einstein A coefficients were taken from the CDMS database, version 2013. For the para moiety, parity doublets were added to match the collision data. Collisional rate coefficients with H2 were scaled from the He-PH3 data by Badri et al. (2020) which cover temperatures in the range from 5 to 100 K for o-PH3 and from 5 to 50 K for p-PH3.
