Canines remain the gold standard for explosives detection in many situations, and there is an ongoing desire for them to perform at the highest level. This goal requires canine training to be approached similarly to scientific sensor design. Developi

RATIONALE The nitrated sugar alcohols mannitol hexanitrate (MHN), sorbitol hexanitrate (SHN) and xylitol pentanitrate (XPN) are in the same class of compounds as the powerful military-grade explosive pentaerythritol tetranitrate (PETN) and the homema

Rationale Techniques for improving the detectability of chlorate and perchlorate salts with thermal desorption based ionizers (i.e. radioactive, corona discharge and photoionization-based) are desired. This work employs acidic reagents to chemically

This work presents a technique by which a low resolution (≈1 nm) fiber-optic spectrometer may be used to definitively identify elements and molecular fragments in laser-induced breakdown spectroscopy. Commercial laser-induced breakdown spectroscopy

We report the first observation of an infrared (v 0,0 ∼4150 cm −1 ) electronic band system arising from excitation of the ground state O 4 − ion, which we discuss in the context of the expected transition (J. Chem. Phys. 114 (2001) 3010) betwee

The mid-infrared predissociation spectra of Cl-·H2O·Arn clusters are dominated by an intense band that is due to excitation of the ionic H-bonded OH stretching vibration. The shape of this band is found to be quite sensitive to the number of attach

The OH stretching bands associated with the ionic H-bond in the Cl-·H2O complex are found to dramatically shift toward higher energy upon complexation with carbon tetrachloride molecules in a size selected photofragmentation study of the Cl-·H2O·(

To explore how a structured excess charge distribution affects the hydration of an anion, we report mid-IR, argon predissociation spectra for the hydrated superoxide cluster anions, O2−⋅(H2O)n, 1⩽n⩽5. This size range was chosen to establish t
