Appendix G. Table of multi-atom probes

The following Symbols may be included in the Directives list for Programme GRID, in order to define a multi-atom Probe. The corresponding properties of the Probes are defined in Subroutine GMULTI in file GRIDF. Users are advised not to alter or edit this Subroutine. (The properties of single-atom Probes are defined in Subroutine GPROBE. Those parameter values in GPROBE may be changed by the User to other reasonable values. The User may also replace the existing single-atom Probes with different ones).

COO-Aliphatic anionic carboxy group
AR.COO-Aromatic anionic carboxy group
CONH2Aliphatic neutral amide group
AR.CONH2Aromatic neutral amide group
CONHRAliphatic neutral amide group*
AR.CONHRAromatic neutral amide group*
AMIDINEAliphatic cationic amidine group
AR.AMIDINEAromatic cationic amidine group
M-DIAMINEMeta-diamino-benzene

* The NH moiety of these Multi-Atom Probes can be either cis or trans with respect to the carbonyl oxygen, and this MUST be specified by the User. The appropriate indicator should be included in the list of Directives before IEND and the job-title like this:

.
.
.
AR.CONHR
CIS
.
.
IEND
Title of the job

If the CIS or TRANS indicator is not specified, the Multi-Atom Probe will behave as if it had a complete NH2 moiety.
