CHE SIGNIFICA MICROWAVE SPECTROSCOPY IN INGLESE
Spettroscopia rotazionale
La spettroscopia rotazionale riguarda la misura delle energie delle transizioni tra stati di rotazione quantizzati di molecole nella fase del gas. Gli spettri delle molecole polari possono essere misurate in assorbimento o emissione mediante spettroscopia a microonde o spettroscopia ad infrarosso. Gli spettri di rotazione delle molecole non polari non possono essere osservati da questi metodi, ma possono essere osservati e misurati con la spettroscopia Raman. La spettroscopia rotazionale è talvolta definita come spettroscopia rotativa pura per distinguerla dalla spettroscopia rotativa-vibrazionale dove si verificano cambiamenti di energia rotazionale insieme a cambiamenti di energia vibrazionale e anche dalla spettroscopia ro-vibronica dove si verificano contemporaneamente cambi di energia rotazionale, vibrazionale e elettronica. Per la spettroscopia rotazionale, le molecole sono classificate secondo simmetria in cima sferica, superiore e lineare e simmetrica; Espressioni analitiche possono essere ottenute per i termini di energia rotazionale di queste molecole. Le espressioni analitiche non possono essere derivate per la quarta categoria, asimmetrica superiore, ma gli spettri possono essere installati utilizzando metodi numerici.
definizione di microwave spectroscopy nel dizionario inglese
La definizione di spettroscopia a microonde nel dizionario è un tipo di spettroscopia in cui le informazioni sono ottenute sulla struttura e sul legame chimico di molecole e cristalli mediante misure delle lunghezze d'onda delle microonde emesse o assorbite dal campione.
