High-resolution laboratory study of the ν2/ν4 bending motion of CH3+ and assignment of its astronomically observed lines

Context. The methyl cation (CH3+) was discovered through the detection of a 7 μm (1400 cm−1) band observed in the d203-506 protoplanetary disk in the Orion nebula using the MIRI-MRS spectrometer on board the JWST. This feature has now been reported in numerous astronomical sources. The initial detec...
