R&D Chemist Interview Questions and Answers for Freshers

Spectroscopy techniques NMR and IR are commonly used in chemistry research and analysis.

• NMR (nuclear magnetic resonance) spectroscopy is used to determine the structure and composition of molecules by analyzing their magnetic properties.

• IR (infrared) spectroscopy is used to identify functional groups in molecules by analyzing their absorption of infrared radiation.

• Both techniques are non-destructive and can be used to analyze a wide range of samples, from small molecules to c...read more

I conducted an experiment to test the effectiveness of a new catalyst in a chemical reaction.

• Designed and set up the experiment to compare the reaction rate with and without the catalyst

• Measured the reaction rate using spectroscopy

• Analyzed the data to determine the impact of the catalyst on the reaction

• Concluded that the catalyst significantly increased the reaction rate
