Why are first and second derivatives important?

In other words, just as the first derivative measures the rate at which the original function changes, the second derivative measures the rate at which the first derivative changes. The second derivative will help us understand how the rate of change of the original function is itself changing.

What is the importance of derivative spectroscopy?

Derivative spectroscopy accomplishes conversion of a normal or zero order spectrums to its first, second or higher derivative spectrum. It yields considerable changes in shape of derivative achieved. Appropriate selection of derivative order gives useful separation of overlapped signals.

What is second derivative spectroscopy?

Second derivative spectroscopy is a technique which enhances the separation of overlapping peaks. The objective of this study was to evaluate the specificity of the second derivative peaks for the main tissue components of articular cartilage (AC), i.e., collagen and proteoglycans (PGs).

What is first derivative spectroscopy?

1] Derivative spectroscopy is the simplest method for an. increasing selectivity is derivatization of spectra. This method is used when the sample of drug shows large. irrelevant absorption. It involves conversion of normal spectrum to its first, second and higher derivative.
