What are the key differences between spectrometry and spectroscopy, and how do these techniques contribute to the analysis of chemical compounds?
Spectrometry involves measuring the intensity of light at different wavelengths, while spectroscopy involves studying the interaction between light and matter. These techniques help identify and analyze chemical compounds by providing information about their molecular structure, composition, and properties. Spectrometry is used to quantify the amount of a substance present, while spectroscopy is used to identify specific functional groups and bonding patterns within a compound. Both techniques are essential in determining the identity and characteristics of chemical compounds in various fields such as chemistry, Biology, and environmental science.
