A graph is a P 4 -indifference graph if it admits a linear ordering โบ on its vertices such that every chordless path with vertices a, b, c, d and edges ab, bc, cd has either a โบ b โบ c โบ d or d โบ c โบ b โบ a. P 4 -indifference graphs generalize indifference graphs and are perfectly orderable. We give a

We generalize and present simplified proofs almost all elementary lemmas from Section 8 of the Odd Order Paper. In many places we use Hall's enumeration principle and other simple combinatorial arguments. A number of related results are proved as well. Some open questions are posed. แฎ 1998 Academic
We have obtained high-resolution Fourier transform emission spectra of the A ห7 X หtransition of the jet-cooled p-xylyl radical in the 450-nm spectral region. The band contours of several vibronic bands are examined. By using the rotational constants obtained from previous high-resolution LIF spectr
