Determine the symmetries of the vibrational bending modes in both cases. Proceed by determining the symmetries of the total degrees of freedom of the molecules. Then obtain the bending modes by subtracting the symmetries of translation, rotation and the three types of bond stretching vibrations. (9 marks) Ascertain whether these two isomers could be distinguished based on the number of non-symmetric bending modes in each isomer. (2 marks) 2. Isomers of 1,2,3-trifluore ay cropreopane F F H H H F F H H Point group of the isomers : Doh. moment. . No permanen dipole Determine the symmetries of the vibrational bending modes in both cases.
