Clustering reactions

CH₄NO⁺ +  = (CH₄NO⁺ • )

By formula: CH₄NO⁺ + CHN = (CH₄NO⁺ • CHN)

Free energy of reaction

CH₄NO⁺ +  = (CH₄NO⁺ • )

By formula: CH₄NO⁺ + H₂O = (CH₄NO⁺ • H₂O)

Bond type: Hydrogen bond (positive ion to hydride)

(CH₄NO⁺ • ) +  = (CH₄NO⁺ • 2)

By formula: (CH₄NO⁺ • H₂O) + H₂O = (CH₄NO⁺ • 2H₂O)

Bond type: Hydrogen bond (positive ion to hydride)

(CH₄NO⁺ • 2) +  = (CH₄NO⁺ • 3)

By formula: (CH₄NO⁺ • 2H₂O) + H₂O = (CH₄NO⁺ • 3H₂O)

Bond type: Hydrogen bond (positive ion to hydride)

(CH₄NO⁺ • 3) +  = (CH₄NO⁺ • 4)

By formula: (CH₄NO⁺ • 3H₂O) + H₂O = (CH₄NO⁺ • 4H₂O)

Bond type: Hydrogen bond (positive ion to hydride)

(CH₄NO⁺ • 4) +  = (CH₄NO⁺ • 5)

By formula: (CH₄NO⁺ • 4H₂O) + H₂O = (CH₄NO⁺ • 5H₂O)

Bond type: Hydrogen bond (positive ion to hydride)
