WebPeak powers in the terawatt range can be generated with devices of still moderate size (fitting into a 20-m 2 room). Large facilities based on multi-stage chirped-pulse amplifiers … WebSep 1, 2024 · Figure 1: The infrared spectrum of high-density polyethylene (HDPE). What was not discussed in the previous column (1) was why the CH 2 rocking peak in HDPE is split, with peaks at 730 and 720 rather having one expected peak at 720±10. To understand this splitting, we need to first examine the spectrum of a mixture of long chain but not ...
