Question

9. Raman vibrational spectrum of PPh-BHb. The same basic information is observed in the infrared spectrum (however our infrared spectrometer cannot observe peaks below 650 cm) 60 r 1027 40 1104 26 1131 1160 13 1182 11 13092 1333 1433 50 476 4951 504 1 806 13002 40 616 10 6231478 7028 766 854 919 1 929 2 999 101 30 157216 20 1585 54 10 1600 1500 1400 1300 1200 1100 1000 900 800 700 600 500 400 Wavenumbers (cm) What key absorption peaks in the Raman spectrum above allow for the unequivocal proof of the B-P covalent bond in PPh BHs?
