Description
  • Infračervená spektra 14 methyl-a polymethyl-substituovaných acetofenonů a 14 stejně substituovaných methylbenzoátů byla zkoumána v oblasti karbonylu. C=O frekvence závisí na induktivním efektu substituentů a ještě více na sterickém efektu ortho substituentů. Sterické efekty nemají jednoduchý vztah k torznímu úhlu fi. Různé fyzikální vlastnosti methyl-substituovaných acetofenonů byly korelovány pomocí analyzy hlavních komponent (cs)
  • Infrared spectra of 14 methyl-and polymethyl-substituted acetophenones and of 14 equally substituted methyl benzoates were investigated in the carbonyl region. The .nu.(C=O) freguency depends on the inductive effect of substituents and more sensitively on the steric effect of ortho substituents. Steric effects are not simply related to the torsion angle fi. Various physical properties of methyl-substituted acetophenones, were correlated by principal component analysis
