Frequency Domain Experiments

We use a single-mode nanosecond pulsed infrared laser in conjunction with a Fourier transform microwave (FTMW) spectrometer to do a variety of double-resonance and triple-resonance meaurements on vibrationally excited molecules. The two main areas of interest using frequency domain techniques are dynamic rotational spectroscopy (DRS) and FTMW-detected IR spectroscopy. Furthermore, we have recently made great strides in improving the technique by which FTMW measurements are made, by building the first truly broadband Fourier transform microwave spectrometer.
