AbstractThe emission spectrum of ArH contains a band near 10 110 cm–1 that appears to be the analogue of the 3d – 4p, v = 0 – 0, band of ArD, observed and analysed near 10 230 cm–1. However, previous attempts to assign the rotational structure of this band of ArH were unsuccessful. Here we observe and analyse the 4f – 3d band of ArH near 4400 cm–1, and are then able to calculate the rotational structure of the 3d – 4p transition entirely from known data. The observed band is similar but not identical to the calculated band. We speculate that the observed spectrum is a v – v sequence band of 3d – 4p, where the v 0 upper state is populated through some mechanism peculiar to this isotopomer.
