WebA : The noise near 4000 to 3400 cm-1 and 2000 to 1300 cm-1 results from the absorption of water vapor (H2O). As the quantity of water vapor fluctuates due to environmental changes, the absorption appears as noise. In addition to water vapor, the absorption by carbon dioxide (CO2) may be observed near 2350 cm-1 and 670 cm-1.
