Figure 4: Comparison of the HOMO and HOMO-1 spectral functions for diamantane possessing a1g and eg symmetry, respectively.
From: Electron–vibration coupling induced renormalization in the photoemission spectrum of diamondoids
The vibration modes contributed dominantly to the largest peak of SF are indicated in milli-electronvolt unit with the corresponding symmetry labels where the motion of the atoms are shown by red arrows for (a) HOMO and (b) HOMO-1 levels. Comparison of the vibrational modes in (c) adamantane and (d) diamantane that couples to the highest occupied molecular orbitals. The motion of atoms in these vibration modes for adamantane and diamantane is shown in the Supplementary Movies 4–6 and 11–13, respectively.
