Fortrat diagrams are commonly use in medium resolution spectroscopy to identify the patterns (or series of related lines such as P, Q, and R branches) along with other false positive matches. Below are the rotational resolved stick spectrum (bottom) and the associated Fortrat diagram of ethynyl radical, C2H, near 1.48 ?m (top) where N’ is rotational quantum number of the excited state. Use your knowledge and identify R branches and P branches in the figure below.
Fortrat diagram illustrates series of branches, branches lines, along with false positive matches with the combination differences of the ground state.
