How to Calculate First overtone frequency?
First overtone frequency calculator uses First overtone frequency=(2*Vibrational Frequency)*(1-3*Anharmonicity constant) to calculate the First overtone frequency, The First overtone frequency formula is defined as the frequency of photons on the first excited state/ overtone band of a diatomic molecule. First overtone frequency and is denoted by v_{0->2} symbol.
How to calculate First overtone frequency using this online calculator? To use this online calculator for First overtone frequency, enter Vibrational Frequency (v_{vib}) and Anharmonicity constant (x_{e}) and hit the calculate button. Here is how the First overtone frequency calculation can be explained with given input values -> -116 = (2*2)*(1-3*10).
