Claim:
1. Instrumentation for detecting for the presence of a molecular species in a sample based on the selective excitation of rotationally dressed states of such species while probing the affected rovibrational transitions of such species, the instrumentation including: a source of electromagnetic radiation for probing the sample to determine both an unperturbed response of the molecular species and a perturbed response of the molecular species; a source of electromagnetic radiation for perturbing the rovibrational density of states of the sample; apparatus for controlling the frequency of the radiation from the perturbing source; a detector for collecting photons that have interacted with the sample as a result of the response to the probing of the sample in the unperturbed and as a result of the perturbing of the sample; and means for determining the effect the perturbation had on the molecular species, the means for determining being coupled to the detector.
