\subsection{Hydrogen bond scans} \label{subsec:HBscan}
Three systems with an N-methylacetamide and a hydrogen bond acceptor were the basis of the \HN hydrogen bond parameterization. The hydrogen bonding system for the negatively charged aspartic $\Delta \sigma_{HB}$ and
glutamic acids side chains were modeled with an acetate anion. The system for bonding with $\Delta \sigma_{H\alpha B}$ (cf. Eq \ref{eqn:procs}) is parameterized using the
alcohol groups of threonine and serine was done with a methanol molecule. The system for bond with another backbone segment was modeled with an additional N-methylacetamide. The \HA scans used a methyl capped alanine peptide to model
the donor residue backbone systems shown in Figures \ref{fig:HB} and
the same three molecules to model the acceptors. See {\bf \ref{supinfo} Supplementary Information} \fref{fig:hbondscans}{\bf-\ref{fig:ALAscans}} for schematics of the model system used. \ref{fig:HAB}. For
\HN $\Delta \sigma_{HB}$ the scan
was are done by scanning over the hydrogen bond length $r_{OH}$, the bond angle
$\theta$ $\theta_{\mathrm{H}}$ defined by H..O=C or H..O-C and the dihedral angle
$\rho$ $\rho_{mathrm{H}}$ defined by H..O=C-N, H..O=C-C or
H..O-C(..)H\textsuperscript{O}. H..O-C(..)H^{O}. The bond length scan was scanned from
$1.5$ \AA\xspace 1.5 to
$4.0$ \AA\xspace 4.0 Å in
$0.125$ 0.125 Å steps.
$\theta$ $\theta_{\mathrm{H}}$ was scanned from
$180$ 180.0 to
$90\deg$ 90.0$\deg$ in
$10\deg$ 10.0 $\deg$ steps and
$\rho$ $\rho_\mathrm{H}$ was done in the entire range
$-180$ -180$\deg$ to
$180$. 180$\deg$.
The \HA hydrogen bonding the scan was done equivalently. The bond length $r_{OH\alpha}$ was scanned from $1.8$ to $4.0$ \AA\xspace in steps of $0.2$ \AA. The bond angle $\theta$ defined by H\(\alpha\)..O=C or H\(\alpha\)..O-C was scanned from $180$ to $90^\circ$ with $10^\circ$ steps size. The $\rho$ dihedral H\(\alpha\)..O=C-N, H\(\alpha\)..O=C-C and H\(\alpha\)..O-C(..)H\textsuperscript{O} was scanned in steps of $15^\circ$ over the entire range.
