Ushbu ishda fenol–formaldegid asosida sintez qilingan kremniyorganik oligomerning infraqizil (IQ) spektroskopik tahlili natijalari keltirilgan. IQ spektrlari yordamida oligomer tarkibidagi organik (fenolik) va noorganik (siloksan) segmentlarga xos bo‘lgan funksional guruhlar aniqlandi. Fenolik birliklarga tegishli O–H cho‘zilish tebranishlari (3200–3550 sm⁻¹), aromatik C=C tebranishlari (1500–1600 sm⁻¹) va C–H cho‘zilish tebranishlari (2800–3000 sm⁻¹) qayd etildi. Kremniyorganik qismning mavjudligi Si–O–Si assimetrik cho‘zilish tebranishlari (1000–1100 sm⁻¹) hamda Si–C bog‘lariga xos signal (800–850 sm⁻¹) orqali tasdiqlandi. Olingan natijalar organik–noorganik interfeysda kovalent bog‘lanishlar hosil bo‘lganini ko‘rsatib, sintez jarayonining samaradorligini baholash imkonini berdi.
