Chiral analysis by mass spectrometry has attracted much attention due to its advantages in
speed, sensitivity and specificity. In this review, recent advances in chiral analysis by mass …

In recent years, methods based on photodissociation in the gas phase have become
powerful means in the field of chiral analysis. Among them, infrared multiple photon …

The amino acid serine has long been known to form a protonated “magic-number” cluster
containing eight monomer units that shows an unusually high abundance in mass spectra …

Spraying solutions of serine under a wide variety of conditions results in unusually abundant
gaseous octamer clusters that exhibit significant homochiral specificity, but the extent to …

The gaseous chiral differentiation of alanine by permethylated β-cyclodextrin was studied
using IRMPD spectroscopy and density functional theory calculations. The protonated non …

The ability of electrospray emitters with submicron tip diameters to significantly reduce and
even eliminate aggregation of analyte molecules that can occur inside evaporating droplets …

The structures of three proton-bound dimers (Met2H+, MetTrpH+, and Trp2H+) are
investigated in the gas phase with infrared multiple photon disassociation (IRMPD) …

For homodimers of amino acids, their salt-bridged structures are gradually stabilized as the
proton affinity of the component amino acid increases. Threonine has a proton affinity value …

We investigate gas-phase structures of homo-and heterochiral asparagine proton-bound
dimers with infrared multiphoton dissociation (IRMPD) spectroscopy and quantum-chemical …

Infrared multiple photon dissociation (IRMPD) spectroscopic and theoretical studies of
protonated homodimers of amino acids generated by electrospray ionization in the gas …
