TYPICAL RANGES FOR PROTONS WITH VARIABLE CHEMICAL SHIFT 

Hydrogens that can exchange either with the solvent medium or with one another also tend to be variable in their absorption positions. The following equations illustrate possible situations  

R—O—H + SOLV H SOLV + R—0= Chapter 8 will discuss all of these situations in more detail.
