    A transparent background should be used. Images should still be readable when scaled down to 450 pixels to prevent conflicts with the Chembox. SVG images are desirable because they are infinitely scalable, while remaining compact. However, support for SVG images among common molecule editors is limited, and may not be rendered correctly on ...

    For example, in most glasses, electrons have no available energy levels above them in the range of that associated with visible light, or if they do, the transition to them would violate selection rules, meaning there is no appreciable absorption in pure (undoped) glasses, making them ideal transparent materials for windows in buildings.
