在紫外可见光谱学的帮助下，可以进行速率测量。从以往与速率测量相关的研究中可以发现，当吸收特性不变时，光谱测量速率的测量包括测量在固定波长处的吸收的下降或上升(Nockemann et al .，2005)。这种测量提供了与反应物或生成物浓度变化相关的信息。紫外可见光谱学最广泛应用的工业应用之一是测量与下降或在吸收固定波长时可能出现的上升有关。不同类型的酶在不同的催化性能上是不容易测量的，但是它们的催化性能可以很容易地在反应的帮助下进行估计，而这些反应实际上是由它们催化的。酶的最广泛应用在临床诊断领域，目的是识别组织损伤。该反应主要应用于烟酰胺腺嘌呤二核苷酸(NAD)的还原(NAD)。
Rate measurements can be done with the help of the UV Visible spectroscopy. From the past studies related to the rate measurement, it can be found that when absorption characteristics are constant, spectrometric rate measurements involve the measurement of the fall or rise in the absorption which are there at a fixed wavelength (Nockemann et al., 2005). This kind of measurements provides the information which is related to the change that is there in the concentration of either the reactants or the products. One of the most widely used industry application of UV Visible spectroscopy is the measurement related to the fall or the rise which may be there in the absorption at a fixed wavelength. The different types of enzymes cannot be easily measured with respect to the different catalytic properties but their catalytic properties easily permit the estimation with the help of the reactions which are actually catalyzed by them. The widest use of the enzymes is in the clinical diagnosis field for the purpose of identification of tissue damage. The reaction is largely used in this process of the reduction of Nicotinamide adenine Dinucleotide (NAD) to (NADH2).
