Proton transfer pathways are indicated by arrows, ‘X’ denotes sites not suitable for proton transfer.
The gas-phase mid-IR spectra of cationic 1,5,9-triazacoronene and two of its cationic derivatives are presented. Their spectra suggest a possible contribution of polycyclic aromatic nitrogen heterocycles to the interstellar aromatic infrared bands.
The [(Et3P)AuCys]+ and [(Et3P)AuSec]+ ions and their deamination products were characterized using IRMPD spectroscopy backed by DFT calculations finding differences in binding motifs and reactivity.
We present the origin of the observed differentiation of lactose and lactulose achieved by complexation with sodiated L-arginine (ArgNa+).
A combination of IR multiple-photon dissociation (IRMPD) action spectroscopy and quantum chemical calculations was employed to investigate the [M,C,2H]+ (M = Fe and Co) species.
