plotted" NMR confirms that Dr. Chen had correctly identified the
sample in 1991/1992.
Later in January 1992, the Analytical Department performed
mass spectral analysis on the sample and the data obtained was "re-
plotted" in 1996 (CX 109). According to Chen et al., the re-plotted
spectra from the testing done in 1992 confirms that Dr. Chen correctly
identified the sample he prepared in late 1991 (CX 64). In March 1992,
Dr. Chen submitted additional samples of the product he prepared in
December 1991 for high resolution mass spectroscopy (HRMS) (CX 118).
Results from the data obtained in 1992 were reprinted in 1996 and that
data allegedly confirms that Dr. Chen correctly identified the product
he prepared in 1991.
In early January 1992, Dr. Chen alleges to have removed the
protecting group from the sample he prepared in December. According to
Dr. Chen's testimony, he recorded the procedure for deprotecting the
earlier prepared compound in his laboratory notebook number 32044-039
(CX 67). Dr. Chen requested that the Analytical Department perform NMR
and MS analysis on the sample. In early January 1992, Ms. Huang
recorded her analysis in her laboratory notebook number 30619 at page
036 (CX 108). According to the testimony of Huang and Rourick (CR 86;
197; CX 69; 108) the spectra were "re-plotted" in 1996 from the raw
data obtained in 1992. Likewise, carbon NMR spectra obtained in 1992
