Detection of Explosive Signature Molecules Using the Rotational Raman Response
Abstract
PO: Joong Kim, PoP: 12 months, PE: 0601153N 6.1N CoreThe proposed research focuses on investigating the laser-induced birefringence"" that occurs after impulsive rotational excitation of gas phase molecules. Birefringent materials, such as quartz, are capable of ma""nipulating the polarization state of a laser beam; for example, transferring linear to circular polarization. A laser-induced time-d"ependent polarization in gas phase molecules can also be used to manipulate the polarization of and/or imprint spectral sidebands on" a probe beam, which can be detected using a simple spectrometer or polarization analyzer. Temple University seeks to explore whethe"r laser-induced rotational revivals in a molecular ensemble and the transient birefringence they create may serve as a means of detecting gas phase signature molecules for improvised explosive devices
