Electronic transitions of XeH were recorded in the infrared with the Fourier transform spectrometer associated with the McMath Solar Telescope at Kitt Peak. XeH was made in a nickel hollow cathode discharge lamp with 100 mTorr of Xe and 2.2 Torr of $H2$. The high-resolution Fourier transform emission spectrum of $a2\Sigma +-2\Pi$ transition near $4400cm-1$ was observed and analysed. The molecular contants were obtained for these two states. Other transitions were observed from $2900-3800cm-1$ and $4600-5000cm-1$.
