Webof the high Q-factor of the resonance in the test object, this can be done after a long enough time so that the front wall echo and its reverberations within the air gap have disappeared. Clearly, the transducer frequency band must encompass at least one of the resonant frequencies of the solid specimen so that WebThis technique is more selective compared to non-resonance Raman spectroscopy. It works by exciting the analyte with incident radiation corresponding to the electronic absorption bands. 2 This causes an augmentation of the emission up to a factor of 10 6 in comparison to non-resonance Raman. 2,3. In this section readers will be introduced to ...
