It has been pointed out that the orbital coefficient a of straight chain and monocyclic conjugated molecules is the sine and cosine function of atom number q:
α=(2/(n+1))^1/2sinωq,α=(2/n)^1/2cosωq
where the angular frequency ω is related to the energy level E:
E=α+2βcosω
The author in his previous work calls the function a=f (q) the carrier wave of molecular orbit (which is a function where the variable is positive integers).
