Infrared Spectrum:

all molecules have a quantised amount of energy

molecules absorb a definite amount of energy

E.g. molecules absorb INFRARED RADIATION the bond VIBRATE?STRETCH more

results are shown on an Infrared Spectrum w/ wavelength (1/cm) on the x-axis and transmittance (%) on the y-axis

wavenumber dec. fromm 4000 - 5000 cm-1

specific bonds absorb pecific wavenumbers

E.g.
