摘要
The association constants for α,α'-dialkylpyrrole:pyridine systems determined from infrared intensity measurements of the NH absorption band of the non-bonded pyrroles indicate that, although the α-substituents sterically hinder the formation of the NH-N bonded complexes, there is little evidence for any significant NH-π bonding. © 1979.
