I developed new tunable coherent infrared source in the mid-infrared (MIR) region that is applicable to supersonic jet infrared spectroscopies. The light source can provides continuous tunability covering 1000-2200cm^<-1> with the output of >0.5mJ/pulse and the energy resolution of <0.4cm^<-1>, which are necessary conditions to perform double resonance spectroscopies on supersonically cooled species.Applications of the MIR laser to the infrared spectroscopy of the skeletal vibrations of several reactive systems, such as phenol-ammonia clusters, methylsalicylate shed new insight into their proton transfer reaction mechanisms that have been inferred only from uninformative broad spectroscopic features.
