Theoretical and Experimental IR Spectra of Astronomical PAHs and PANHs in the 2000-1650 cm-1 Range (∼5-6 μm)

{{output}}
Recent James Webb Space Telescope observations reveal unprecedented details in the 2000-1650 cm-1 (∼5-6 μm) region, including the well-known 5.25 and 5.75 μm bands. This range, dominated by overtone and combination bands mainly involving C-H out-of-plane (C... ...
