WebOct 26, 2016 · A lack of water molecules interacting means hydrogen bonds aren't forming. Moving to a bulk phase, where the water molecules are now interacting with each other all the time, hydrogen bonds are being formed … WebMay 6, 2024 · a) Experimental procedure. Infrared spectroscopy, or IR spectroscopy, involves the casting of infrared light through a molecular sample. The energy from the light then causes covalent bonds within the molecule to vibrate. These bonds can vibrate by stretching and bending. As the light passes through the sample, a spectrometer measures …
