hello there,
i've read in several places the following: if you have a polyene with J double bonds, and taking into account that the average C-C length is aprox 140 pm, then the length of the box is:
L=2J*140
And I don't get why 2? the number of bonds is not 2J, but 2J-1, for cases such as hexatriene"!
HEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEELP!
thanks :)
