coordinate type specified in line 43. The<br />

second field is the FORTRAN format of the<br />

atom coordinates.<br />

9. Lines 45–65 each contains three fields<br />

describing the Cartesian coordinates of an<br />

atom indicated in the CT block. The first field<br />

is the X coordinate, the second field is the Y<br />

coordinate and the third field is the Z<br />

coordinate.<br />

SYBYL MOL File<br />

The SYBYL MOL File format (SYBYL) is defined<br />

in Chapter 9, “SYBYL File Formats”, pages 9–1<br />

through 9–5, of the 1989 SYBYL Programming<br />

Manual.<br />

The following is an example of a file in SYBYL<br />

format produced from within Chem3D. This file<br />

describes a model of cyclohexanol.<br />
