Spectrum 1 corresponds to the photon spectrum of detector 1. You can see the position/opening of the detectors in the Info item of a simulation.

If you want to compare transmitted and backscattered photons, I would suggest creating two annular detectors:
1) one with a polar angle from 0 to 90 deg
2) another with a polar angle from 90 deg to 180 deg.
