During femtosecond laser fabrication, photons are mainly absorbed by electrons, and the
subsequent energy transfer from electrons to ions is of picosecond order. Hence, lattice …

Conspectus Mass spectrometry is a powerful analytical method capable of identifying
compounds given a minute amount of material. The fragmentation pattern that results …

Strong-field laser-matter interactions often lead to exotic chemical reactions. Trihydrogen
cation formation from organic molecules is one such case that requires multiple bonds to …

Ultrafast science depends on different implementations of the well-known pump–probe
method. Here, we provide a formal description of ultrafast disruptive probing, a method in …

Roaming chemical reactions are often associated with neutral molecules. The recent
findings of roaming processes in ionic species, in particular, ones that lead to the formation …

We develop a new model to simulate nonradiative relaxation and dephasing by combining
real-time Hartree–Fock and density functional theory (DFT) with our recent open-systems …

2-Nitrotoluene (2-NT) is a good model for both photolabile protecting groups for organic
synthesis and the military explosive 2, 4, 6-trinitrotoluene (TNT). In addition to the direct C …

We introduce an atomistic, all-electron, black-box electronic structure code to simulate
transient absorption (TA) spectra and apply it to simulate pyrazole and a GFP-chromophore …

A standard sample mixture containing 51 pesticides was separated by gas chromatography
(GC), and the constituents were identified by mass spectrometry (MS) using femtosecond …

We present UV photofragmentation studies of the structural isomers paracetamol, 3-
Pyridinepropionic acid (3-PPIA) and (R)-(-)-2-Phenylglycine. In particular, we utilized a new …
