Gas Phase Heat Capacity (Shomate Equation)

C_p° = A + B*t + C*t² + D*t³ + E/t²
H° − H°_298.15= A*t + B*t²/2 + C*t³/3 + D*t⁴/4 − E/t + F − H
S° = A*ln(t) + B*t + C*t²/2 + D*t³/3 − E/(2*t²) + G
    C_p = heat capacity (cal/mol*K)
    H° = standard enthalpy (kcal/mol)
    S° = standard entropy (cal/mol*K)
    t = temperature (K) / 1000.

Clustering reactions

CN^- +  = (CN^- • )

By formula: CN^- + H₃B = (CN^- • H₃B)

 +  = ( • )

By formula: H^- + H₃B = (H^- • H₃B)

H₄B^- +  = (H₄B^- • )

By formula: H₄B^- + H₃B = (H₄B^- • H₃B)
