The transition energy for an absorption line in the electromagnetic spectrum is the energy difference between two quantum states of an atom or molecule involved in the absorption process. It corresponds to the specific wavelength or frequency of light absorbed when an electron transitions from a lower energy level to a higher one. This energy can be calculated using the equation ( E = h \nu ) or ( E = \frac{hc}{\lambda} ), where ( E ) is the transition energy, ( h ) is Planck's constant, ( \nu ) is the frequency, ( c ) is the speed of light, and ( \lambda ) is the wavelength. Each element or molecule has unique absorption lines characteristic of its electronic structure.

What would be the approximate wavelength (in nm) of the 3T1 3T2 transition in a complex with Δo 29040cm-1 and B968 cm-?
To find the approximate wavelength of the 3T1 to 3T2 transition, we can use the formula ( \lambda = \frac{1}{\nu} ), where ( \nu ) is the energy in wavenumbers (cm^-1). The energy difference for the transition can be approximated as ( \Delta E \approx \Delta_o ) for this case, which is 29040 cm^-1. Converting this to wavelength, we have: [ \lambda = \frac{1}{29040 , \text{cm}^{-1}} \times 10^7 , \text{nm/cm} \approx 344.3 , \text{nm}. ] Thus, the approximate wavelength of the 3T1 to 3T2 transition is around 344 nm.
