Infrared luminescene method is similar a similar phenomenon in which a mineral absorbs visible light and emits the energy as invisible light while
Infrared reflected method absorption spectroscopy (IRAS, IRRAS) is an optical technique used to study thin (often submonolayer) films adsorbed on reflective substrates such as metals.
Explanation:
Hope this helps
Additional: infrared reflected method reflect while infrared liluminescene method absorbs
Uhh if d tama yung additional dont put in na kase not that sure lol:p
