8. The spectral bandwidth of a pulse at the transform limit is dictated by the Heisenberg relation ΔE × Δt ∼ h/2π, implying that short pulses have very large bandwidths. Consequently, many materials (e.g., solvents, glass walls of cuvettes, etc.) cause sub-picosecond pulses to become temporally broadened ("chirped") as they propagate through the medium. In order to minimize this effect, optical paths of 1 mm or less are typically used in these experiments.

41. Since there is no matrix element that provides for direct mixing between states differing by two spin quanta, one must invoke second-order spin-orbit interactions (i.e., S = 0/S = 1 and S = 1/S = 2) in order to realize a ΔS = 2 conversion.
