The PolySense team has just published a new article on Photoacoustics Journal Elsevier (IF 9.94) reporting on a study of the non-radiative relaxation dynamic of 12CH4 and 13CH4 in wet nitrogen-based
matrixes by using the quartz-enhanced photoacoustic spectroscopy (QEPAS) technique. We demonstrated that QEPAS measurements can be used to retrieve both the effective relaxation rate in the matrix, and the V-T relaxation rate associated to collisions with nitrogen and water vapor.
