Paper Abstract

By directly measuring the absorption spectrum of the chemicals in the vapor phase, we are able to fingerprint molecules. This process is made possible by frequency-tuning a widely-tunable THz source developed by us recently. In the THz region, we have demonstrated that we can use a set of the absorption peaks due to rotational transitions to truly fingerprint chemical species.
