摘要：

Infrared absorption bands in neon, argon, and krypton matrices at 4 K were assigned to Si-3, Si-4, Si-6, and Si-7 from isotopic splittings and from ab initio calculations of their vibrational frequencies and relative intensities. The agreement between experimental and calculated frequencies is excellent. Si-5 is apparently in too low a concentration to be observed.
