TL;DR: In this paper, the authors measured the SmO+ bond energy by monitoring the threshold for photodissociation of the cryogenically cooled ion, which has important implications on the reactivity of Sm atoms released into the upper atmosphere.

TL;DR: In agreement with previous work, deamidation is facilitated by anchimeric assistance of the thio group, which also leads to an interesting rearrangement of the intact amino acid identified computationally.

TL;DR: The SmS+ bond energy is compared with theoretical values characterized at several levels of theory, including CCSD(T) complete basis set extrapolations using all-electron basis sets and multireference configuration interaction calculations with explicit spin-orbit calculations along with composite thermochemistry using the Feller-Peterson-Dixon method.

TL;DR: Comparisons between the IRMPD and theoretical IR spectra indicate that 18C6 binds to Gly and His via the protonated backbone amino group, whereas protonation Lys prefers binding via the Protonated side-chain amino group.
