What is the different of C-F, C-F2 and C-F3 bond in C1s or F1s of XPS result?

I was measured the XPS of my FeF2 coated by carbon and got the XPS results of 288.5 eV and 292eV in C1s which were correspond to the C-F and C-F2, also in my F1s contain that peak of C-F and C-F2...

What is your perception on using visual analysis or quantitative approaches to evaluate data from single-case research designs (n of 1 trials)?

Results of single-case research designs (i.e., n-of-1 trials) are often evaluated by visually inspecting the time-series graph and computing quantitative indices. A question our research team is...
