Clustering reactions

C₅H₁₀NO₂⁺ +  = (C₅H₁₀NO₂⁺ • )

By formula: C₅H₁₀NO₂⁺ + C₅H₁₁NO₂ = (C₅H₁₀NO₂⁺ • C₅H₁₁NO₂)

C₅H₁₂NO₂⁺ +  = (C₅H₁₂NO₂⁺ • )

By formula: C₅H₁₂NO₂⁺ + C₅H₁₁NO₂ = (C₅H₁₂NO₂⁺ • C₅H₁₁NO₂)

 +  = ( • )

By formula: Na⁺ + C₅H₁₁NO₂ = (Na⁺ • C₅H₁₁NO₂)

Notice: Except where noted, spectra from this collection were measured on dispersive instruments, often in carefully selected solvents, and hence may differ in detail from measurements on FTIR instruments or in other chemical environments. More information on the manner in which spectra in this collection were collected can be found here.

Notice: Concentration information is not available for this spectrum and, therefore, molar absorptivity values cannot be derived.
