Infrared (IR) versus Terahertz (THz) Absorption Strengths for Chemical Species Associated with Homeland Security


EMSL Project ID
26717

Abstract

We will measure the absolute infrared (IR) and terahertz (THz) absorption oscillator strengths of several species of interest associated with homeland security to assess the relative merits of the IR vs. THz sensing regimes.
