Kent ; Kaitchuck, Ronald H. ; Schlegel, Eric M. Abstract Whole-orbit, time-resolved spectrophotometry of 18 cataclysmic variables is reduced and displayed in a homogeneous fashion. Each set of digital data is binned into a phase-dependent gray-scale image which resembles a single-trailed photographic spectrogram. This technique permits convient comparison of phase-dependent spectral changes among the different systems. The approximate wavelength interval 4250-4950 A was observed at 2.5 A resolution. This interval contains the accretion disk emission lines of H-beta, H-gamma, He I 4471 A, and He II 4686 A. A brief commentary on the phenomena that can be seen in the image of each star is given. These effects include orbital motion, line-profile changes during eclipse, and s-waves. Several epochs of data on UX UMa are presented, displaying yearly changes in the spectrum. A series of outburst spectra of RX And are included, showing how phase-dependent spectra evolve during outburst. EX Hya spectra are displayed folded on both the 98 minute and the 67 minute photometric periods. In all, 23 spectral data sets are displayed and discussed for the 18 systems.
