"Infatuation" has a slightly different meaning distinct from "love" while "limerence" is a distinct and precise form of "love". Just like love can be an umbrella term for a number of similar but different emotions (love like siblings, love between parents and children, love between friends, etc.), "limerence" might also be called a "crush" or "puppy love" (if I read the article correctly). I think you can probably use it loosely as a synonym with infatuation in most contexts but the meaning is ever so slightly different. I never heard it before today either, English has a far too many words.
