non-dispersive infrared spectroscopies

https://doi.org/10.1351/goldbook.08643
Kinds of infrared spectroscopy in which the effect of the sample on the radiation from the source is measured as a whole without exploring the dependence on wavenumber.
Note:
These methods are mainly used to obtain adequate optical throughput for process measurement and monitoring.
Example:
Two-dimensional infrared correlation spectroscopy.
