Effect of high pressure on critical concentration energy transport in isotopically mixed naphthalene crystals

High pressure has been observed to enhance significantly triplet energy transfer from naphthalene-h/sub 8/ traps to ..beta..-methylnaphthalene supertraps in a naphthalene-d/sub 8/ crystal near the critical trap concentration, as indicated by supertrap/trap phosphorescence ratios. This suggests the i...

Zusammenfassung:	High pressure has been observed to enhance significantly triplet energy transfer from naphthalene-h/sub 8/ traps to ..beta..-methylnaphthalene supertraps in a naphthalene-d/sub 8/ crystal near the critical trap concentration, as indicated by supertrap/trap phosphorescence ratios. This suggests the importance of long-range interactions in triplet transport in this crystal system. 16 references, 1 figure, 1 table.
