- •
Line shape parameters for 2v3 Q branch manifolds of 12CH4 near 6000 cm−1 are obtained.
- •
Temperature dependences of air- and self-broadened widths and shifts are reported.
- •
Off-diagonal relaxation matrix element coefficients are measured for 15 transition pairs.
- •
Widths, shifts and temperature dependences are compared to HITRAN2012 values.
- •
Positions for 104 and intensities for 109 transitions are also obtained.
