Aweome! very didactic video both part 1 and part 2 to understand the basics of the TAS technique and its components.
Thank you very much:)

This is very informative video. Thank you so much from beginners like us, for making such a video to easily understand TA kinetics. I have a question, it will be great if you could answer me,
1. what second derivative of absorption spectra indicates as it has same feature as that of TA spectra?

Very nice video, thank you. You said that for dye molecules the lifetime from TAS and from TRPL are expected to be the same. For TAS, the emission is stimulated and the effective lifetime depends upon the pump intensity (photon density of states), but for TRPL it is a spontaneous emission (or counting also nonradiative channels) lifetime. Can you please comment upon your experience of this.

@13:15 ∆A = log ( Ip / Ip+p )

[@sajinponnan9290]

log(x) - log (y) = log (x/y)

[@MastermindofBCB]

I_p and I_(p+p) in your formula are the respective transmittances of probe and pump+probe? If so, I agree. 👍

I was just about to question myself. Thanks for commenting :)
