Chirped pulses allow for non‐adiabatic passage between dressed states of Raman processes. It is shown that using an appropriately chirped pulse, one can control the interference between resonant and non‐resonant pathways in stimulated Raman processes. A three‐level system is studied in detail and application to complete ro‐vibrational level inversion to high vibration quantum numbers ( v > 10) in H 2 via RCNAP (Raman chirped non‐adiabatic passage) is presented.
