WebJan 25, 2024 · UV-vis spectra of the DR81 dye diluted in water (10 µM), at different pHs. In the visible range, the dye solution exhibited a maximal light absorbance at around 510–518 nm depending on the pH. It was red from pH 4.5 to pH 10.7 (λ max around 510 nm) and red-purple at strong alkaline pH (12.3) (λ max = 517.5 nm). WebIn the early 20th century, the astronomer Edwin Hubble observed that the spectra of distant galaxies were significantly redshifted (such as below). Hubble interpreted this shift in the spectrum as a Doppler shift, postulating that these …
