consider butadiene [itex] H_2 C = CH-CH=cH_2 [/itex] and assume for simplicity that [itex] \pi [/itex] electrons move on a straight line (one -dimensional box) whose length l can be estimated as equal to two [itex] C=C [/itex] bond lengths (2*1.35 angstrom) , plus one [itex] C-C [/itex] lengths. Butadiene has four [itex] \pi [/itex] that fill the [itex] n=1 [/itex] & [itex] n=2 [/itex]. the transition observed in a UV/VIS spectrum thus corresponds to the exitationof ane electron from the [itex] n = 3 [/itex] state. Experimentally one finds that this corresponds to the absorption of light with a wavelengths of 217 nm. Compute and compare the lenghts of the 0ne-D box suggested by the sum of the bond length and by the energy of the transition.
