The infrared spectrum of solid methyl azide has been obtained in the region from $1000cm-1$ to $400cm-1$ using LiF, NaCl and KBr prisms in Perkin-Elmer Models 21 and 112 Spectrometers Samples were in the form of thin films which were observed at liquid nitrogen temperature in a conventional low-temperature cell. In general in the spectrum of the solid support the interpretation of the spectrum of the gas by Mantica and $Zerbi1$ and the of gaseous deutero-methyl azide by Miller and $Bassi.2$ However several minor changes in assignments are suggested. Evidence of hydrogen bonding and of partial orientation in the solid is provided by the present study.
