In this article, we present results from ab initio molecular dynamics simulation of overtone excitation in formic acid monomer and its water complex in the gas phase. For the monomer, a conformation change is observed employing both OH and CH vibrational excitations, which supports experimental findings. In the formic acid–water complex, interconversion also takes place, but it proceeds via hydrogen exchange rather than via intramolecular reaction. Simulations raise a question on effect of quantum and matrix effects to the results. Also, a brief test of different computation methods was done on the system.

Ab initio molecular dynamics studies of Au38(SR)24 isomers under heating
Juarez Mosqueda, Rosalba; Malola, Sami; Häkkinen, Hannu (Springer, 2019)Despite the great success in achieving monodispersity for a great number of monolayer-protected clusters, to date little is known about the dynamics of these ultra-small metal systems, their decomposition mechanisms, and ... -
Growth, single crystal investigations, Hirshfeld surface analysis, DFT studies, molecular dynamics simulations, molecular docking, physico-chemical characterization and biological activity of novel thiocyanic complex with zinc transition metal precursor
Makhlouf, Jawher; El Bakri, Youness; Valkonen, Arto; Saravanan, Kandasamy; Ahmad, Sajjad; Smirani, Wajda (Elsevier, 2022)The present work undertakes the study of novel thiocyanic complex, which have been obtained due to the interaction of cationic entities with the thiocyanate ligands. In fact, these latter are added to a transition metal ... -
Selective recognition of aromatic hydrocarbons by endo-functionalized molecular tubes via C/N-H⋅⋅⋅π interactions
Huang, Guo-bao; Liu, Wei-Er; Valkonen, Arto; Yao, Huan; Rissanen, Kari; Jiang, Wei (Elsevier Ltd; Chinese Chemical Society, 2018)Molecular recognition of aromatic hydrocarbons by four endo-functionalized molecular tubes has been studied by 1H NMR spectroscopy, computational methods, and single crystal X-ray crystallography. The binding selectivity ... -
Multi-scale dynamics simulations of molecular polaritons : the effect of multiple cavity modes on polariton relaxation
Tichauer, Ruth H.; Feist, Johannes; Groenhof, Gerrit (AIP Publishing, 2021)Coupling molecules to the confined light modes of an optical cavity is showing great promise for manipulating chemical reactions. However, to fully exploit this principle and use cavities as a new tool for controlling ... -
Explicit proton transfer in classical molecular dynamics simulations
Wolf, Maarten G.; Groenhof, Gerrit (Jossey Bass, Ed. & Pub., 2014)We present Hydrogen Dynamics (HYDYN), a method that allows explicit proton transfer in classical force field molecular dynamics simulations at thermodynamic equilibrium. HYDYN reproduces the characteristic properties of ...
