Research Fields
Optical Studies of Mixed Organic Crystals at Low Temperatures. Experiments were performed to measure the optical spectra of organic molecules including wavelengths, intensity measurements, and lifetimes of the phosphorescence at temperatures from 1.8 deg K degrees above absolute zero to 200 deg K. Molecules studied include: Benzene, Toluene, and other fluorescent and phosphorescent organic molecules. Isotopes of Benzene were studied in the range from 1.8 deg K to 40 deg K. The electron spin lattice relaxation of the benzene molecule in the excited triplet state was studied from 1.8 deg K to 10 deg K.
Master's Thesis: Near Ultraviolet Spectra of Benzene in Frozen Cyclohexane Solutions
Doctoral Thesis: Temperature Effects on the Phosphorescence of Benzene, Toluene, and Pyrazine

Interests and Hobbies
Computers - Currently Running a Pentium 866 with 128 Meg with a 40 Gig hard drive. Using photo quality color printers, 21" monitor, CD writer backup, and cable modem and CD ROM. Operating system is Windows ME. Have a small network with 4 computers connected at home. Use a variety of software packages including various graphics and media programs. On line email address is NKilmer@kscable.com. Using Microsoft Internet Explorer as a Web Browser at home. Constructing these web pages using the FrontPage2000. Currently enjoy videoconferencing using Microsoft's Netmeeting and playing Links LS2000 Golf games. Also have begun writing CD's with music and video and doing graphics work with a digital camera. When traveling I use my notebook computer for communications and a GPS system for directions.
Amateur Radio - Hold an Advanced Class License with call letters, NOLRA. Operate an HF station operating on 7 bands and a VHF/UHF station operating on 2 meters and 440 MHz bands. Serve as net control for the Mennonet, a group of Mennonite Ham Radio Operators, which meets on Sunday pm at 3:00 CST on or about a frequency of 14,290 kHz. Also am trustee of the Hesston College Amateur Radio Club repeaters which operate on 145.21- MHz and 442.4+ MHz.
Alternative Energies - Have interest in Solar Energy. Designed a solar collector using air as a medium. Live in a house with solar heating system. Especially like renewable energy sources. Published an article on The Thermal Performance of the Hesston College Solar House in the Journal of Heating and Cooling.
