The analysis of RTS in this paper quantitatively explains details of charge carriers trapping and detrapping processes in MOS structures. The emphasis is on those RTS showing a capture process, which deviates from the standard Shockley-Read-Hall kinetics. With a shorter observation time (number of RTS pulses - 7x105) the capture and emission time constants exactly follow an inverse carrier density dependence predicted by the standard Shockley-Read-Hall kinetics (SRH). On the other hand, with longer observation times (the number of pulses - 15x106 - more than 30 hours), the second emission process, which continues a parallel with the capture process ?c, is observed and simple SRH theory is disclaimed. Thus was proved that the occupation time probability density for the emission is given by a superposition of two exponential dependencies, whereas the capture time constant distribution is purely exponential. The distributions of the times in the 'high' and 'low' states according to SRH kinetics are exponential, in semi-logarithmic plot the histograms of the 'high' and 'low' states has the linear decay.
