   Traditionally, students probe the PIB model by measuring the UV-vis absorption of conjugated carbocyanine dyes. 
   This experiment links chain length to π-π* transition energies via an analytical formula in comparison to experimental spectra. 
   To deepen engagement and conceptual understanding, an updated version of the experiment integrates computational chemistry with classic laboratory techniques. 
-  Students can connect molecular orbital theory to the restriction of electron motion to discrete energy levels by comparing the computationally determined $λ_{max}$ to the experimentally collected spectra. 
+  Students can connect molecular orbital theory to the restriction of electron motion to discrete energy levels by comparing the computationally determined λ_max to the experimentally collected spectra. 
   Additionally, the use of Python introduces valuable skills in coding, data analysis, and visualization. 
   Together, these elements create a multifaceted learning experience that reinforces core physical chemistry concepts through modern computational tools.
