This is a repeating pattern of single and double bonds between carbon atoms. 1 of 8 What is the name given to the group responsible for colour in molecules? Chromophore 2 of 8 What are spectroscopic techniques used for? They are very important fr the determination of the structure of organic compounds, as well as assessing their purity. 3 of 8 How is it that we see blue light? All light except blue light has been absorbed out of the white light. 4 of 8 How is it that we see red light? All light except red light has been absorbed out of the white light. 5 of 8 What is the trends for wavelength, frequency and energy as you go from violet to red light? The wavelength increases and the frequency and energy decreases. 6 of 8 What is the trend for wavelength and frequency as you go from gamma to radio waves? The wavelength increases and the frequency decreases. 7 of 8 What part of the spectrum does NMR cover? NMR covers the top end of the spectrum, where the wavelength is longer [microwaves / radiowaves] 8 of 8
