众所周知，含有孤对的化合物在溶剂化过程中，其n-π*电子跃迁发生蓝移（高能量）。通常用来解释这种蓝移的原因是，由于其空间范围，孤电子对与溶剂相互作用，或者像在非质子溶剂中那样弱，或者像在水或醇中那样通过直接形成氢键而强。本文的目的是表明，这种解释至多是不完整的，而且在许多情况下是不正确的
It is well-known that compounds containing lone pairs undergo a blue shift (higher energy) in their n-π* electronic transition upon solvation. The reason generally put forth to explain such a blue shift is that the lone pair, because of its spacial extent, interacts with the solvent, either weakly, as in aprotic solvents, or strongly through the direct formation of hydrogen bonds, as with water or alcohols. It is the purpose of this communication to suggest that this explanation is at best incomplete and, in many cases, incorrect
