- what are the vibrational bands of ASA?Draw the lewis structure and describe the bondong in Cr2(CH3COO)4(H2O)2 using MO theory. In the Raman spectrum an intensive line at 556 cm-1 is observed. Assign this band and calculate the force constant using the approach that only two atoms are involved in this vibration.Which has a lower characteristic stretching Frequency, the C=O bond or band C-O bond.
- Compute for the predicted frequency of the strongest band in the IR spectrum of molecule 3H19F, if the strongest band of molecule 2H19F has a frequency of 9.99 × 1013 Hz.The IR spectrum of HCN shows three strong absorption band at 3312 cm⁻¹, 2089 cm⁻¹ and 712 cm⁻¹ from this information alone can you deduce whether HCN is linear or nonlinear? Assuming that HCN is linear assign vibration to the three absorption bands.The stretching frequencies for H2, HD, and D2 are 4395, 3817, and 3118 cm-1 respectively. Why? Explain.
