Piezospectroscopic studies of the triplet states of RbMnF3

2014 We present piezospectroscopic studies of the absorption bands due to the 6A1g ~ 4T1g(I, II), 4T2g(I, II) optical transitions of RbMnF3. For the 4T2g unstructured absorption band we have deduced the coupling parameters involving the Eg and T2g modes of vibration. The piezospectroscopic behaviour of the 6A1g ~ 4T1g(I) magnetic dipole transition is analysed to directly obtain the coupling parameters which are found to be in agreement with our previous calculations.
