1 Electronic Supplementary Material (ESI) for New Journal of Chemistry. This journal is The Royal Society of Chemistry and the Centre National de la Recherche Scientifique 2015 Molecular structure, spectral analysis and hydrogen bonding analysis of ampicillin trihydrate: A combined DFT and AIM approach Eram Khan, Anuradha Shukla, Anubha Srivastava, Shweta, Poonam Tandon * Electronic supplementary information New Journal of Chemistry Date 3D MEP of the monomer of AT calculated from optimized structure is shown in Fig. S1. Fig. S2 shows the HOMO and LUMO of monomer and its energy gap. The molecular graph of monomer of AT using AIM program is given in Fig. S3. The experimental and calculated geometric parameters of monomer and dimer of AT is given in Table S1. Selected Lewis orbitals with percentage ED over bonded atoms, hybrid NBOs with s and p character in % for monomer of AT are listed in Table S2. The calculated static dipole moment (µ 0 ), the mean polarizability ( α 0 ), the anisotropy of the polarizability (Δα), the mean first order hyperpolarizability (β 0 ) and their components for monomer and dimer of AT, using B3LYP/ G(d,p) are given in Table S3. The thermodynamic properties at different temperatures for monomer of AT is given in Table S4. Table S5 gives the information about the theoretically calculated total energy (ev), zero-point energy (J/mol), enthalpy (kcal/mol), specific heat (cal.mol 1 K 1 ), entropy (cal.mol 1 K 1 ) and rotational constants (GHz) at K for monomer and dimer of AT. The geometrical parameters for hydrogen bonds in dimer of AT are given in Table S6. Table S7 gives the theoretical and experimental vibrational wavenumbers (cm -1 ) of AT with potential energy distribution (PED).
