Cs2 molekula Lāzera inducētā fluorescence A~b komplekss Fizika Furjē transformācijas spektroskopija

description

Šajā bakalaura darbā tika pētīts Cs2 molekulas 〖A^1∑〗_u^+ un 〖b 〗^3 Π_u stāvokļu komplekss ar lāzera inducētās fluorescences un Furjē transformāciju spektroskopijas metodēm. Veicot darba uzdevumus tika apgūta lāzera inducētās fluorescences (LIF) pieeja sārmu divatomu molekulu pētīšanai, izmantojot spektrometru (Bruker IFS-125HR) un titāna-safīra lāzera sistēmu (MBR 110, Coherent). Eksperimentālajām iekārtām tika veikti sagatavošanas un uzstādīšanas darbi, lai varētu detektēt LIF spektrus ar Furjē spektrometru. Iegūtie mērījumi par Cs2 molekulas 〖A^1∑〗_u^+ ~ 〖b 〗^3 Π_u kompleksu tika izanalizēti izmantojot darbā aprakstītās spektru apstrādāšanas metodes. Darba rezultātā iegūti ~2000 rotācijas kvantu skaitļi J’ enerģijas diapazonā 11620-13440 cm-1, kas ievērojami paplašina Cs2 molekulas A~b kompleksa eksperimentālo datu lauku.
