Enhanced Vibrational Echo Correlation Spectrometer for the Study of Molecular Dynamics, Structures, and Analytical Applications
Abstract
Funds from a DURIP equipment grant were used to augment the ultrafast IR 2D vibrational echo spectrometer. The major improvement involved a new dual MOT array detector composed of two 32 x 1 element MCT IR detector arrays. The dual array makes it possible to improve signal-to-noise ratio in the heterodyne detection of the vibrational echo signal. To implement the revamping of the system, new optics to implement the two beam geometry were put in place and precision translation stages required to control the path lengths to fractions of a wavelength of light obtained. The instrument has been used make the first measurements of ultrafast chemical exchange, making in possible to study fast solute solvent complex dynamics and isomerization in room temperature solutions under thermal equilibrium conditions.
