Spectra were collected in transmission mode using a 12H\u2010NEC\/catalyst\/KBr mixture pellet to overcome the difficulty of introducing low\u2010volatility 12H\u2010NEC. A peak\u2010deconvolution, assignment, and normalization protocol was developed to interpret the complex C\u2500H stretching region from 3100 to 2750\u00a0cm\n                    <jats:sup>\u22121<\/jats:sup>\n                    . The results indicate that dehydrogenation begins at the five\u2010membered ring and that species spectroscopically consistent with 8H\u2010NEC accumulate at approximately 100\u00b0C. A transient spectral state observed before this accumulation is consistent with an earlier partially dehydrogenated intermediate, for which 10H\u2010NEC is one possible structural assignment. This work provides experimental insight into the dehydrogenation mechanism of 12H\u2010NEC under mild conditions and may guide further efforts to improve the hydrogen\u2010storage performance of 12H\u2010NEC\u2010based LOHC systems.\n
