Research Description

Dr. Raston performs laser spectroscopy of helium solvated molecules and clusters. This includes the use of homebuilt helium nanodroplet isolation spectrometer for investigating molecules and clusters that are relevant to combustion, the atmosphere, or interstellar space. Superfluid helium nanodroplets perhaps provide the ultimate medium for the study of chemical dynamics at the molecular level. Their low temperature, enormous heat conductivity, and weakly interacting nature allow for the formation of species that are often inaccessible by conventional synthetic means. The following animation shows an example of the kinds of systems we are interested in (in this case, the exchange reaction between HCl and OH).
