A broad peak in this region typically indicates the presence of O-H stretching vibrations in alcohols or phenols.

The O-H bond in alcohols and carboxylic acids typically shows a strong absorption around 3300 cm-1 due to the stretching vibration.

Ketones typically show a strong carbonyl (C=O) absorption around 1700 cm-1 due to the stretching vibration.

A higher absorbance indicates a higher concentration of the analyte, as per the Beer-Lambert Law.

One of the main advantages of UV-Vis spectrophotometry is that it can measure very low concentrations of analytes in solution.

UV-Vis spectroscopy primarily observes electronic transitions, where electrons move between different energy levels.

A spectrophotometer is the instrument commonly used to measure absorbance in UV-Vis spectroscopy.

Determining molecular weight is not a common application of IR spectroscopy; it is primarily used for identifying functional groups and studying molecular vibrations.
