Morphology
The compound meaning is directly derivable from 'absorption' (the process of taking up energy/substance) + 'spectrum' (a band of wavelengths): it denotes a spectrum characterized by absorption at specific wavelengths. This compositional pattern is common in scientific terminology and parallels constructions in other languages, so a B1 learner who knows both constituents can grasp the basic meaning even if detailed technical specifics require further domain knowledge.
Etymology
Absorption spectrum comes from a simple picture: think of white light as a rainbow, a spectrum or 'range of colours', and imagine a gas that 'takes in' some colours — that absorption leaves dark lines where those colours are missing. That's why an absorption spectrum is a picture showing which colours of light were absorbed.
