Multiphoton electron extraction spectroscopy (MEES) is an analytical method in which UV laser pulses are utilized for extracting electrons from solid surfaces in multiphoton processes under ambient conditions. Counting the emitted electrons as a function of laser wavelength results in detailed spectral features, which can be used for material identification.

In recent study, MEES was found to be sensitive and indicative to some molecular skeleton features such as hydrogen bonding, rigidity, aromaticity and steric hindrance. This uniqueness as well as other spectroscopic trends allow sensitivity as well as selectivity among a variety of energetic materials and other NO_x based compounds

Short Biography of Presenting Author

Dr. Danny Fisher received his M.Sc. in Chemistry from Bar Ilan University (under the supervision of Prof. A. A. Frimer), and his Ph.D. from the Technion (under the supervision of Prof. I. Schechter). His Ph.D. thesis was on the development and applications of multiphoton electron extraction spectroscopy (MEES). Previously, he conducted a multidisciplinary research related to trace explosives detection and the mechanism of particle adhesion and removal from surfaces. He was awarded the Teva award for excellent research in analytical chemistry
