Nonlinear shift of the resonance at the E line of the P(7) transition of the ν3 band in methane
Bagaev S. N., Mal'tsev S. V., Chebotaev V. P.
The first observation is reported on nonlinear behavior in the impact shift of the resonance at the Ε line in methane as a function of the gas pressure; the shift falls off abruptly in the low-pressure region (—1 mTorr).
