Infrared spectroscopy of gas-phase hydrogenated and methylated pyrenes: from laboratory spectra to the simulated 3.4 $\hat{I}¼$m emission band

Karine Demyk, Christine Joblin, Louan de Bentzmann +2

Observations of the aromatic infrared emission band at 3.3 $\hat{I}¼$m often reveal satellite emission features in the 3.4 - 3.6 $\hat{I}¼$m range. While the 3.3 $\hat{I}¼$m band is attributed to th…
