Summary

自动翻译

Vengono descritti i dettagli di generazione e ottimizzazione del segnale, misurazione, acquisizione dei dati e gestione dei dati per uno spettrometro Raman stimolato a IR risolto al tempo del femtosecondo. Uno studio Raman stimolato vicino all'infrarosso sulle dinamiche di stato eccitato del carotene z nel toluene è mostrato come un'applicazione rappresentativa.
