Question 1

molecular ion peak

Answer 1

indicates the species formed from the molecule by the loss of one electron

Question 2

fragmentation

Answer 2

occurs when the molecular ion breaks into smaller pieces

Question 3

base peak

Answer 3

indicates the peak with the greatest abundance

Question 4

infrared radiation

Answer 4

the part of the electromagnetic spectrum with frequencies below that of red light

Question 5

when does stretching occur?

Answer 5

when a bond absorbs infrared radiation and uses it to alter the length of the bond

Question 6

transmittance

Answer 6

transmittance value in an infrared spectrum represents the amount of radiation absorbed at a particular wavenumber

Question 7

wavenumber

Answer 7

represents the frequency of infrared radiation absorbed by a particular bond in a molecule

Question 8

intensity

Answer 8

describes the amount of infrared radiation absorbed
