Scope and content
"Some infrared bands of [CH2F2] and CH2ClF have been observed in the near infrared (PbS region). For all observed bands of both molecules, the [RQ] and [RQ] branches have been resolved and the molecular [A-1/2(B+C] determined. For one [type -C] band of [CH2F2], [PP] and [RR] branches were resolved, and for this molecule, the [1/2 (B+C)] molecular constant was determined. From these parameters the molecular dimensions were calculated. The [2.219u] band of [CH2F2] presents an aysmmetric shape in the strong, unresolved [Q] branch, and it is shown that this asymmetry is due to the fact that [CH2F2] molecule is a slightly asymmetrial top".
