Thank you for your explains, Just a question: In case we need both smoothing and normalizing, which one should we run and process at the first? smoothing before normalizing or viceversa?
To find the band gap, you would typically look for the onset of absorption or the point where the intensity starts to increase significantly. The band gap represents the energy difference between the valence band and the conduction band in a material. In the plot, you can identify the wavelength corresponding to this onset point, and then use the relationship E = hc/λ (where E is energy, h is Planck's constant, c is the speed of light, and λ is the wavelength) to calculate the band gap energy. Regarding electron affinity, the normalized intensity vs. wavelength plot may not directly provide information about it. Electron affinity refers to the energy change when an electron is added to a neutral atom or molecule to form a negatively charged ion. It is typically measured as the energy difference between the highest occupied molecular orbital (HOMO) and the vacuum level. Experimental techniques like photoelectron spectroscopy or computational methods are commonly used to determine electron affinity. Thanks
@@SAYPhysics Thank you very much for your reply. The onset of absorption starts from initial significant increase in Intensity to max points of intensity? Also regarding electron affinity, which plot should we use for measuring it? And How?
You can check in the playlist, there are videos on inset in a plot and merging two or more plots in one graph. I'm pasting links to the two above-mentioned videos, while the rest you may see in the OriginLab tutorial playlist.... th-cam.com/video/t2_wMkILto8/w-d-xo.html th-cam.com/video/2xfFS5rWvMo/w-d-xo.html
Welcome. When you right click on a column and select normalize. Under the normalization menu, normalization method drop menu has many options. The first one is to normalize wrt specific value. Thanks
Thank you so much prof for your effort, please it is possible to add a graph on an existing merged graphs in origin? i hope my question would be replied, thanks.
Thanks Mahaman. Yes, you can add. Open the project where you have the merged graphs. If the graph to be added is in the same project, go to merge option again and select the specified plot. If the graph is in another project, watch this video to accomplish the task. Thanks th-cam.com/video/k4pCw0lvd2Q/w-d-xo.html

What to do if I also want to maintain the proper intensity heights after normalization? Somehow some of my peak heights change (some of the peaks reach 1, when in reality, the peaks are gradually increasing) after separate normalization and then combining them like your technique. Please reply
@ichigo kurosaki Whenever you normalize e.g. 0 to 1, the min intensity will be at 0 and max at 1 for each profile. To keep max values as actual while min at 0, you'll have to subtract baseline from each individually and then plot together. See the following video for details.Thanks th-cam.com/video/qJOhLqaSby8/w-d-xo.html
Any data for which you discuss the difference in magnitudes on the y-axis, that's, your focus of discussion is on the scaling of y-axis, you can't normalize such data. Thanks
If you're talking about the Legends in a Plot, you can see them in many of my videos in the playlist. In case you just want to add text, you can do it from the text (written as T on the ribbon at left side). This video may help you (th-cam.com/video/rVNMm9VGKjE/w-d-xo.html)
Quite helpful, Thank you for providing it :))
Great. Thanks
gracias, busque en varios videos y aquí encontré lo que buscaba: normalizar :D
Thanks for the appreciation dear

Thanks for the appreciation dear. First you may normalize and then smooth it.

How can we find band gap and electron affinity from this normalized intensity vs wavelength plot??
To find the band gap, you would typically look for the onset of absorption or the point where the intensity starts to increase significantly. The band gap represents the energy difference between the valence band and the conduction band in a material. In the plot, you can identify the wavelength corresponding to this onset point, and then use the relationship E = hc/λ (where E is energy, h is Planck's constant, c is the speed of light, and λ is the wavelength) to calculate the band gap energy.
