Calculation of atmospheric molecular backscatter coefficient at specified pressure, temperature and wavelength.

1	betamol(P, T, lambda = 1064)

`P`	Pressure in hPa. can be scalar, vector or matrix of the same dimension of T.
`T`	Temperature in °k. can be scalar, vector or matrix of the same dimension of P.
`lambda`	Scalar value in nm. It represent the wavelength of incident light.

Return according to the dimension of P and T returns the volume backscatter coefficient [1/m 1/sr] for the specified wavelength lambda.
