Defines a spatial reference object based upon its well known text string (WKT) and optionally a WKT for a vertical datum. The resolution and xy tolerances are either computed from the sr horizon or set to defaults. The output sr is always high precision.

Remarks
Finds a predefined spatial reference based on its OGC/EPSG
definition string, otherwise known as its well-known text string
(WKT). The text string contains individual parameters
of a spatial reference. A valid spatial reference for a
geographic coordinate system (GEOGCS) may appears as
follows:
GEOGCS["GCS_WGS_1984",DATUM["D_WGS_1984",SPHEROID["WGS_1984",6378137.0,298.257223563]],PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]]
Note the nested structure of parameters includes a datum, spheriod,
prime meridian, and angular unit.
A valid spatial reference for a projected coordinate system
(PROJCS) may appears as follows:
PROJCS["World_Mercator",GEOGCS["GCS_WGS_1984",DATUM["D_WGS_1984",SPHEROID["WGS_1984",6378137.0,298.257223563]],PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]],
PROJECTION["Mercator"],PARAMETER["False_Easting",0.0],PARAMETER["False_Northing",0.0],PARAMETER["Central_Meridian",0.0],PARAMETER["Standard_Parallel_1",0.0],UNIT["Meter",1.0]]]
Note the nested structure of parameters includes a geographic
coordinate system (GEOGCS), a projection, and a set of projection
parameters such as false easting, false northing, and standard
parallel.
If
WKT_Z is specified and not empty, then a vertical
coordinate system will be created and associated with the
horizontal coordinate system. The definition string can be
generated from ArcObjects using the ExportToESRISpatialReference
method on a PCS or GCS. The boolean parameters are as described for
FindSRByWKID.
