Determination of the water vapor continuum absorption by THz
... However, the gated and coherent detection of THz-TDS [18,19] can avoid the continuous thermal noise background, thereby giving a much higher sensitivity at room temperature than the incoherent liquid helium cooled bolometers of FTS. Another powerful advantage of THz-TDS is that the electric field pu ...

Ultraviolet–visible spectroscopy
Ultraviolet–visible spectroscopy or ultraviolet-visible spectrophotometry (UV-Vis or UV/Vis) refers to absorption spectroscopy or reflectance spectroscopy in the ultraviolet-visible spectral region. This means it uses light in the visible and adjacent (near-UV and near-infrared [NIR]) ranges. The absorption or reflectance in the visible range directly affects the perceived color of the chemicals involved. In this region of the electromagnetic spectrum, molecules undergo electronic transitions. This technique is complementary to fluorescence spectroscopy, in that fluorescence deals with transitions from the excited state to the ground state, while absorption measures transitions from the ground state to the excited state.
