The intermediate decomposition products of methanol (CH3OH) in an AC discharge were diagnosticated via concentration modulation spectroscopy. Several main vibrational bands of CO Angström beta 1 sigma+ -alpha 1pi system, CH alpha 2 delta-X2pi system at 430 nm and beta 2 sigma- -X2pi at 390 nm, as well as CHO (329.82 nm), CH2O (369.

Article Synopsis
- An experimental setup utilizing an AC discharge was created to generate a molecular ion beam, primarily focusing on N2+ ions.
- The emission intensity of N2+ was found to be significantly stronger than that of N2, achieving a high ratio of 6:1 in N2 discharge.
- The study also involved analyzing the effects of N2 discharge, along with calculating the vibrational and rotational temperatures of N2+ ions as 3,310 K and 282 K, respectively, based on the emission spectra.
