Fizika lāzer-inducētā fluorescence Furjē transformācijas spektroskopija RbCs molekula tripleta stāvoklis

description

Šajā bakalaura darbā tika pētītas pārejas RbCs molekulā no A^1 Σ^+~b^3 Π kompleksa uz a^3 Σ^+ un X^1 Σ^+ stāvokli. Pētījuma metode bija lāzer-inducētās fluorescence kombinācijā augstas izšķiršanas spējas Furjē transformāciju spektru reģistrāciju. RbCs molekulas tika ierosinātas izmantojot titāna-safīra lāzeru. Reģistrētajos lāzer-inducētās fluorescences spektros tika novērotas intensīvas pārejas uz singleta stāvokli X^1 Σ^+ un ārkārtīgi vājas pārejas uz tripleta a^3 Σ^+ stāvokli no kopīga A-b kompleksa līmeņa. Tika noteikti relatīvie intensitāšu sadalījumi pētāmajās progresijās, kā arī novērtēta summārā intensitāšu attiecība (sazarošanās attiecība) starp pārejām uz tripleta un singleta stāvokļiem. Eksperimentālie rezultāti tiek salīdzināti ar teorētiskiem aprēķiniem.
