Silane (SiH4) was observed in IRC +10216 by
Goldhaber & Betz
in 1984 using the strong rotation-vibration transitions in a band near 917 cm-1.
Subsequent confirmations of silane in IRC +10216 were made by
Keady and Ridgway and
Monnier et al. It
has evidently not been observed in any other source.
Silane is a periodic cousin of
methane and shares the same tetrahedral structure.
It is used industrially for
glass coatings and in semiconductor manufacture. It is
pyrophoric: it combusts spontaneously in air at room
