When it loses three electrons to become <strong>Ti\u00b3\u207a<\/strong>, two electrons are removed from the 4s orbital and one from the 3d orbital, resulting in the configuration <strong>[Ar] 3d\u00b9<\/strong>. This means the Ti\u00b3\u207a ion has <strong>one electron in the 3d orbital<\/strong>.<\/p>\n\n\n\n<p>In the complex ion <strong>[Ti(H\u2082O)\u2086]\u00b3\u207a<\/strong>, the Ti\u00b3\u207a ion is surrounded by six water molecules, forming an <strong>octahedral geometry<\/strong>. In an octahedral field, the five degenerate 3d orbitals split into two energy levels: the <strong>lower energy t\u2082g orbitals<\/strong> (dxy, dxz, dyz) and the <strong>higher energy e\u2099 orbitals<\/strong> (dx\u00b2\u2212y\u00b2, dz\u00b2).<\/p>\n\n\n\n<p>Since Ti\u00b3\u207a has only one 3d electron, this electron occupies a t\u2082g orbital. The absorption of light promotes this electron from a t\u2082g to an e\u2099 orbital. This type of electronic transition is known as a <strong>d-d transition<\/strong>.<\/p>\n\n\n\n<p>The absorption spectrum of [Ti(H\u2082O)\u2086]\u00b3\u207a is <strong>not sharp<\/strong> because of several factors:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Vibronic coupling<\/strong>: The electronic transition occurs simultaneously with vibrational transitions of the complex. This interaction produces a <strong>band<\/strong> rather than a single line.<\/li>\n\n\n\n<li><strong>Jahn-Teller distortion<\/strong>: Although weak for d\u00b9 systems, slight distortions from perfect octahedral symmetry may cause a <strong>splitting of the e\u2099 or t\u2082g levels<\/strong>, leading to an absorption peak with a <strong>shoulder<\/strong>.<\/li>\n<\/ol>\n\n\n\n<p>Therefore, instead of one sharp absorption, the complex shows a <strong>broadened peak with a shoulder<\/strong>, reflecting the complex electronic and vibrational interactions within the coordination compound.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"852\" height=\"1024\" src=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-7.jpeg\" alt=\"\" class=\"wp-image-24694\" srcset=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-7.jpeg 852w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-7-250x300.jpeg 250w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-7-768x923.jpeg 768w\" sizes=\"auto, (max-width: 852px) 100vw, 852px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>What is the electronic configuration of the Ti3+ ion?
