Answer
A. Directly proportional to the Square root of force constant
B. Inversely proportional to the square root of force constant
c. Directly proportional to the square root of reduced mass reduced mass
D. Inversely proportional to the square root of reduced mass
Answers
Answer:
molecular vibration is a periodic motion of the atoms of a molecule relative to each other, such that the center of mass of the molecule remains unchanged. The typical vibrational frequencies range from less than 1013 Hz to approximately 1014 Hz, corresponding to wavenumbers of approximately 300 to 3000 cm−1.
Answer:
Directly proportional to the Square root of force constant
Explanation:
Diatomic molecules have normal vibrational modes because only single bonds can be stretched or compressed.
Molecular vibrations are excited when a molecule absorbs an energy ΔE corresponding to a vibrational frequency ν according to the Planck constant h relationship ΔE = hν.
Molecular vibrations are periodic movements of the atoms of a molecule relative to each other such that the center of gravity of the molecule does not change. Typical vibrational frequencies range from less than 1013 Hz to about 1014 Hz, which corresponds to wavenumbers of about 300 to 3000 cm-1.
Hence, the Vibrational stretching frequency of a diatomic molecule is Directly proportional to the Square root of force constant
