Answer to Question #167881 in Physical Chemistry for Sunil giri

Question

Using the particle in a box model, the wavelength of electromagnetic radiation needed to excite electronically to the first excited state, a linear polyene of length 12 angstroms and containing 8 π-electrons (me = 9.11 x 10^-31 kg), is:?

Answer 1

Recall that the probability of finding a particle at x = 0 or x = L is zero. To determine A, recall that the total probability of finding the particle inside the box is 1, meaning there is no probability of it being outside the box.
