This tutorial review presents the technique of infrared multiple-photon dissociation (IRMPD)
spectroscopy of mass-selected trapped ions. This requires coupling of a tunable infrared …

Several approaches to ion activation in tandem mass spectrometry have been developed in
recent years for use in ion trapping instruments that allow for conditions to be reached …

The feasibility of a novel technique for efficient and selective population transfer from a
thermally populated level 1 via an intermediate state 2 to level 3 is experimentally …

Photodissociation induced by the absorption of single photons permits the detailed study of
molecular dynamics such as the breaking of bonds, internal energy transfer and …

Intramolecular vibrational energy transfer is a process central to many physical and
chemical phenomena in molecules. Here, various theories describing the process are …

Could there be chiral methane? What is the characteristic structural feature (in a
physicochemical sense) of a molecule? This question dates back to Louis Pasteur, the …

The ability of Paul and Penning traps to contain ions for time periods ranging from
milliseconds to minutes allows the trapped ions to be subjected to laser irradiation for …

Cryogenic ion trap vibrational spectroscopy paired with quantum chemistry currently
represents the most generally applicable approach for the structural investigation of …

Due to the rapid development of portable, wearable and implantable electronics in the fields
of mobile communications, biomonitoring, and aerospace or defense, there is an increasing …

The experimental and theoretical studies of the microwave ionization of highly excited
hydrogen atoms provide a unique opportunity to explore two new frontiers of modern …
