WebAug 24, 2024 · In transmission, the pathlength has sharp boundaries, at the windows or sides of a pellet. In contrast, the intensity of the ATR evanescent wave decays exponentially with distance from the surface—there is no sharp cutoff. Harrick defined dp as the point at which the intensity of the evanescent wave has dropped off by 1/e or roughly 1/3. Webcontact Harrick Scientific immediately.
