Infrared Spectroscopy

Question 1

what does infrared radiation cause?

Answer 1

the covalent bonds to vibrate more and absorb energy

Question 2

what does absorption of infrared by atmospheric gases do?

Answer 2

atmospheric gases: C=O, O-H and C-H(e.g. H2O,CO2,CH4)
- suspected link to global warming and resulting changes to energy usage

Question 3

what are the uses of infrared spectroscopy?

Answer 3

• monitor gases causing air pollution(e.g. CO and NO from car emissions)
• modern breathalysers to measure ethanol in breath
