I agree, probably "fascination peak is a "Tortured Phrase", but now look what Google's AI tells us about the use of this term👇 ...citing these junk science products as reference to claim that "fascination peak" is in fact a term in spectroscopy 😱

👉"fascination peak" of the "crucial state" in UV/Vis absorption spectra

UV-Vis Absorption up to a wavelength of 0 nm = infinite energy!!

...one can publish EVERYTHING 👇 now in #ChemSky, nobody cares... authors, reviewers, editors, publishers, readers, what a disaster 😮‍ ...but PLEASE don't cite me in such context!
