The bending vibration of water (H₂O) appears at 1595 cm⁻¹, while that of deuterium oxide (D₂O) appears at 1178 cm⁻¹. The symmetric stretching frequencies are 3657 cm⁻¹ for H₂O and 2671 cm⁻¹ for D₂O. Both modes show significant isotope effects. What is the primary physical reason that bending modes are sensitive to hydrogen isotope substitution?
