Below, I posted a short video explaining how we observe rotation in the time domain. Please note that the video does not explain the quantum mechanical principles required to describe molecular rotation, but gives a pseudo-classical picture. This picture does not explain why molecular rotation is quantized or how we can relate rotational frequencies to molecular structure.
Here is a guide for CRASY data analysis, written for a UNIST lab course: PC_lab_course_CRASY_Schultz.pdf. You can find an installation guide for the data analysis software on page 6 and a guide for CRASY data analysis on the following pages. If you want to learn more about the CRASY experiment, navigate to the crasy.org landing page. Required Software You will require the following software: (1) Python (I suggest to install the “Miniconda” package.) (2) The crasyPlots program. If you have trouble installing or running the software, watch the walk-through video below. Data […]
Rotational Raman spectra as sound files.
The following are some resources that may help you with your scientific writing. Scientific writing can be a challenge even for native writers, so don’t despair. Practice makes perfect and you have to write to learn to write. If you have to write a report, please use a template and submit your report with double line spacing for easier correction. I propose the template from JACS for MS Word or Latex. To master structure and style, please refer to the relevant Style Guides. Here is a short 1-page cheat sheet […]
The introduction slides for the lab course can be found on the UNIST Blackboard system. Vibrational absorption frequencies for common chemical groups are listed in the IR_correlation_table. Relevant vibrational Raman reference spectra  are summarized in this document: Literature Raman spectra. You can ask questions to the teaching assistants 인호 (email@example.com) and Begum Ozer (firstname.lastname@example.org).

The translation stage ‘Standa 960-0060’ sells for $399 and offers a full-step resolution of 1.25 micrometer (200 steps/turn, 250 micrometer per turn). With factor 8 or 16 microstepping, the resolution should be sufficient for interferometric experiments with visible light (156 or 78 nm resolution). The stepper can be easily controlled with an Arduino-based USB controller for a cost of less than $40, but a little soldering is required.
