Abstract
Observations on the near‐infrared absorption spectrum of solid methane in the region of ν1+ν4 and ν3+ν4 over a temperature range of 6° to 33°K are presented and discussed. There is no evidence of molecular rotation, and the observations are shown to lead to an interpretation involving an order‐disorder transition. Approximate f numbers for the transitions are measured.Keywords
