Chapter 14: Chemical Kinetics
... For a reaction to occur as a result of a specific collision, the collision must have enough energy to overcome the energy barrier (activation energy). As you saw in Gases (Unit 10) and Intermolecular Forces and the Liquid State (Unit 11), the molecules in a given sample have a Boltzmann distribution ...

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.
