WebATR spectrum show a marked shift to lower frequencies. The expanded ATR spectrum is shown in Figure 3, together with the transmission spectrum and the advanced correction spectrum for comparison. The transmission spectrum of polycarbonate shows bands at 1232 cm-1, 1194 cm-1, and 1164 cm-1. In the diamond ATR spectrum, these bands … Webspectrum. Unlike transmission measurements, ATR sampling does not produce totally absorbing spectral bands because the effective path-length is controlled by the crystal properties thereby minimiz-ing sample re-preparation time. After the spectrum has been col-lected, which should typically take no more than 32 seconds, the user
