Why is near infrared spectroscopy used?

Answer 1

Because many organic compounds absorb in the infrared.

The frequency at which a particular bond will resonate or vibrate is determined by its length and tightness (think of strings in music).

In the electromagnetic spectrum, each frequency is associated with a wavelength, or color. Many organic compound bonds resonate with wavelengths that are slightly outside of the visible spectrum, or infrared.

Near-infrared spectroscopy is used because it allows for the rapid and non-destructive analysis of a wide range of organic and inorganic compounds. It is particularly useful in fields such as chemistry, pharmaceuticals, agriculture, and food science for qualitative and quantitative analysis of samples.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
