Infrared spectroscopy ., Transmission , Absorption, Wave NumberAbstract
IR , MIR , UV - Visible spectra have been studied for Cobalt chloride molecule ( CoCl2 6H2O) compound . In wide range spectra ( 40000 - 410 ) cm-1 specially MIR range. Assignment were achieved for the fundamental vibrational bands of ( CoCl2 . 6H2O) to symmetry stretching Anti - symmetry stretching , these bands are non degenerate , and the bending band is V2 ( n ) is doubly degenerate thought they have activity in IR and Raman , which explain the weakness in symmetry of this molecule , the fundamental bands for the molecule are centered at the following wave numbers ( 488.5, 590 , 1000 , 1057 1330 , 1624.06 . 2050, 2320 , 2363,2400,3344 ) cm-1 which are corresponding to wave lengths ( 20470,16949.10000 , 9460 , 7518,6157,4878.4310, 4232,4166, 2990 ) nm. The UV and visible spectra of the shows bands centered at ( 202.7 ) nm . ( 49431 ) cm-1 due to the electronic transitions in , other bands centered at ( 394.4 , 720.8 ) nm , ( 25354 , 13873 ) cm-1 due to an electronic transitions.
