Espèces réactives et intermédiaires (7) - Louis Fensterbank (2025-2026)

Whole-channel inclusion: Physique et chimie - Collège de France is an honest teaching channel (title sample + 3 transcripts read: All three samples lack transcripts, so the whole verdict relies on the prior title-sample assessment confirming this is a genuine academic lecture archive from Collège de France.); this title passed a strict title check (sonnet) after a labelling pass.
