Mass spectrometry |
An analytical technique used to identify compounds and their molecular formula |
|
|
High resolution mass spec |
- More sensitive form of mass spec - Allows Mr of substance to be determined to several decimal places - Precise atomic masses always given & can then be used calculate the molecular formula of compound tested |
|
|
Infrared Spectroscopy |
-Uses infrared (IR) radiation to determine functional groups present in organic compounds - IR radiation passed through sample where different types of bonds absorb the radiation in digfferent amounts - Varying amount of absorbance are measured & recorded- allows certain bonds & therefore, |
