We use time-resolved coherent Raman spectroscopy to obtain molecule-specific signals from dipicolinic acid (DPA), which is a marker molecule for bacterial spores. We use femtosecond laser pulses in both visible and UV spectral regions and compare experimental results with theoretical predictions. By exciting vibrational coherence on more than one mode simultaneously, we observe a quantum beat signal that can be used to extract the parameters of molecular motion in DPA. The signal is enhanced…

Discrimination of dipicolinic acid and its interferents by femtosecond coherent Raman spectroscopy
Measurements of the beat frequencies between vibrational modes of dipicolinic acid (DPA) and a series of other molecules (interferents) are presented. The results were obtained from femtosecond
Sensitive femtosecond coherent anti-Stokes Raman spectroscopy discrimination between dipicolinic acid and dinicotinic acid.
We demonstrate that femtosecond ultraviolet and visible coherent anti-Stokes Raman spectroscopy provides the sensitivity and specificity needed to distinguish between two similar molecules of
Concentration dependence of femtosecond coherent anti-Stokes Raman scattering in the presence of strong absorption
We study near-resonant femtosecond coherent anti-Stokes Raman scattering (CARS) of dipicolinic acid (DPA) by exciting the molecular system with a pair of visible pump and Stokes pulses and probing
Resonant UV-fs-TCFWM spectroscopy on formaldehyde.
UV-fs-TCFWM experiments which involve resonant transitions to the rovibrational manifolds of the C-O stretch and out-of-plane combination bands in the first electronically excited singlet state of H2CO at energies close to the HCO production threshold are discussed.
Effect of nuclear motion on the absorption spectrum of dipicolinic acid.
Using semiclassical electron-radiation-ion dynamics, the authors have examined the effect of nuclear motion, resulting from both finite temperature and the response to a radiation field, on the line
