Read moreIn today’s post we’ll discuss why most molecules are colourless, introduce the useful technique of UV-visible spectroscopy, and finally explain why molecules like chlorophyll and β-carotene
Read moreIn our last post we showed that molecules with C-C pi (π) bonds absorb light in the UV-visible region, which promotes electrons from (bonding) π orbitals to
Read moreIn the past few posts we’ve covered some of the key points of UV-Vis spectroscopy. Now comes the key question: how do we apply it?
