Abstract

The molecular exciton model has received its most extensive development and application in the field of molecular crystals1'2. More recently, numerous applications to non-crystalline molecular composite systems have been made, including van der Waals and hydrogen-bonded dimers, trimers, and

Contenuto in sintesi

Riassunto in italiano preparato leggendo l'abstract (https://www.degruyterbrill.com/document/doi/10.1351/pac196511030371/pdf (non accessibile: 405/403/Cloudflare)); non è un testo dell'autore originale.

Obiettivo e tipo di lavoro

Contributo teorico-spettroscopico (Pure Appl. Chem. 1965, 11, 371-392; atti dell'VIII Congresso Europeo di Spettroscopia Molecolare, Copenaghen) sul modello eccitonico molecolare. Il testo completo non è stato letto: il PDF non era accessibile.

Contenuto in sintesi

Poiché il testo non è stato letto, si riporta solo quanto emerge da descrizioni secondarie: il lavoro è considerato un classico del modello eccitonico per un dimero (van der Waals) di molecole identiche, che spiega come le interazioni deboli tra molecole generino nuove caratteristiche negli spettri degli aggregati. Per il contenuto dettagliato (geometrie, splitting, regole di selezione) consultare direttamente l'articolo.

Risultati e conclusioni principali

Non verificabili senza il testo. È il riferimento storico da cui nascono i concetti di aggregato H e J.

Collegamento con la tesi

Citata (rif. 58) alla sez. 4.5 (riga 1260): la tesi usa la teoria dell'accoppiamento eccitonico di Kasha per distinguere aggregati H (face-to-face) e J (head-to-tail) e afferma che gli aggregati H presentano una transizione permessa verso lo stato eccitonico a più alta energia, quindi uno spostamento ipsocromico e una emissione ridotta. Per approfondire occorre la parte sul dimero eccitonico (splitting degli stati, regole di selezione in funzione della geometria).

Note del revisore: Testo completo non ottenuto: de Gruyter 405/403 da WebFetch, IUPAC dietro Cloudflare. Il riassunto non va considerato una lettura dell'articolo.

Come è citata nella tesi

• Sez. 4.5 Caratterizzazione spettroscopica allo stato solido (tesi.md r. 1260): Nei polimeri coniugati, le forti interazioni π-π favoriscono frequentemente la formazione di aggregati H, i quali presentano una transizione otticamente permessa verso lo stato eccitonico a maggiore energia.[58]
